where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

2. License Grants and Conditions
2.1. Grants
Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
a. under intellectual property rights (other than patent or trademark)
Licensable by such Contributor to use, reproduce, make available,
modify, display, perform, distribute, and otherwise exploit its
Contributions, either on an unmodified basis, with Modifications, or as
part of a Larger Work; and
b. under Patent Claims of such Contributor to make, use, sell, offer for
sale, have made, import, and otherwise transfer either its Contributions
or its Contributor Version.
2.2. Effective Date
The licenses granted in Section 2.1 with respect to any Contribution become
effective for each Contribution on the date the Contributor first distributes
such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under this
License. No additional rights or licenses will be implied from the distribution
or licensing of Covered Software under this License. Notwithstanding Section
2.1(b) above, no patent license is granted by a Contributor:
a. for any code that a Contributor has removed from Covered Software; or
b. for infringements caused by: (i) Your and any other third party’s
modifications of Covered Software, or (ii) the combination of its
Contributions with other software (except as part of its Contributor
Version); or
c. under Patent Claims infringed by Covered Software in the absence of its
Contributions.
This License does not grant any rights in the trademarks, service marks, or
logos of any Contributor (except as may be necessary to comply with the
notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this License
(see Section 10.2) or under the terms of a Secondary License (if permitted
under the terms of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its Contributions
are its original creation(s) or it has sufficient rights to grant the
rights to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under applicable
copyright doctrines of fair use, fair dealing, or other equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
Section 2.1.
3. Responsibilities
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under the
terms of this License. You must inform recipients that the Source Code Form
of the Covered Software is governed by the terms of this License, and how
they can obtain a copy of this License. You may not attempt to alter or
restrict the recipients’ rights in the Source Code Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
a. such Covered Software must also be made available in Source Code Form,
as described in Section 3.1, and You must inform recipients of the
Executable Form how they can obtain a copy of such Source Code Form by
reasonable means in a timely manner, at a charge no more than the cost
of distribution to the recipient; and
b. You may distribute such Executable Form under the terms of this License,
or sublicense it under different terms, provided that the license for
the Executable Form does not attempt to limit or alter the recipients’
rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for the
Covered Software. If the Larger Work is a combination of Covered Software
with a work governed by one or more Secondary Licenses, and the Covered
Software is not Incompatible With Secondary Licenses, this License permits
You to additionally distribute such Covered Software under the terms of
such Secondary License(s), so that the recipient of the Larger Work may, at
their option, further distribute the Covered Software under the terms of
either this License or such Secondary License(s).
3.4. Notices
You may not remove or alter the substance of any license notices (including
copyright notices, patent notices, disclaimers of warranty, or limitations
of liability) contained within the Source Code Form of the Covered
Software, except that You may alter any license notices to the extent
required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on behalf
of any Contributor. You must make it absolutely clear that any such
warranty, support, indemnity, or liability obligation is offered by You
alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Software due to statute, judicial
order, or regulation then You must: (a) comply with the terms of this License
to the maximum extent possible; and (b) describe the limitations and the code
they affect. Such description must be placed in a text file included with all
distributions of the Covered Software under this License. Except to the
extent prohibited by statute or regulation, such description must be
sufficiently detailed for a recipient of ordinary skill to be able to
understand it.
5. Termination
5.1. The rights granted under this License will terminate automatically if You
fail to comply with any of its terms. However, if You become compliant,
then the rights granted under this License from a particular Contributor
are reinstated (a) provisionally, unless and until such Contributor
explicitly and finally terminates Your grants, and (b) on an ongoing basis,
if such Contributor fails to notify You of the non-compliance by some
reasonable means prior to 60 days after You have come back into compliance.
Moreover, Your grants from a particular Contributor are reinstated on an
ongoing basis if such Contributor notifies You of the non-compliance by
some reasonable means, this is the first time You have received notice of
non-compliance with this License from such Contributor, and You become
compliant prior to 30 days after Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions, counter-claims,
and cross-claims) alleging that a Contributor Version directly or
indirectly infringes any patent, then the rights granted to You by any and
all Contributors for the Covered Software under Section 2.1 of this License
shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
license agreements (excluding distributors and resellers) which have been
validly granted by You or Your distributors under this License prior to
termination shall survive termination.
6. Disclaimer of Warranty
Covered Software is provided under this License on an “as is” basis, without
warranty of any kind, either expressed, implied, or statutory, including,
without limitation, warranties that the Covered Software is free of defects,
merchantable, fit for a particular purpose or non-infringing. The entire
risk as to the quality and performance of the Covered Software is with You.
Should any Covered Software prove defective in any respect, You (not any
Contributor) assume the cost of any necessary servicing, repair, or
correction. This disclaimer of warranty constitutes an essential part of this
License. No use of any Covered Software is authorized under this License
except under this disclaimer.
7. Limitation of Liability
Under no circumstances and under no legal theory, whether tort (including
negligence), contract, or otherwise, shall any Contributor, or anyone who
distributes Covered Software as permitted above, be liable to You for any
direct, indirect, special, incidental, or consequential damages of any

# DOMPurify
[](http://badge.fury.io/js/dompurify)  [](https://www.npmjs.com/package/dompurify)  [](https://github.com/cure53/DOMPurify/network/dependents) [](https://cloudback.it)
DOMPurify is a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG.
It's also very simple to use and get started with. DOMPurify was [started in February 2014](https://github.com/cure53/DOMPurify/commit/a630922616927373485e0e787ab19e73e3691b2b) and, meanwhile, has reached version **v3.3.3**.
DOMPurify runs as JavaScript and works in all modern browsers (Safari (10+), Opera (15+), Edge, Firefox and Chrome - as well as almost anything else using Blink, Gecko or WebKit). It doesn't break on MSIE or other legacy browsers. It simply does nothing.
**Note that [DOMPurify v2.5.9](https://github.com/cure53/DOMPurify/releases/tag/2.5.9) is the latest version supporting MSIE. For important security updates compatible with MSIE, please use the [2.x branch](https://github.com/cure53/DOMPurify/tree/2.x).**
Our automated tests cover [28 different browsers](https://github.com/cure53/DOMPurify/blob/main/test/karma.custom-launchers.config.js#L5) right now, more to come. We also cover Node.js v20.x, v22.x, 24.x and v25.x, running DOMPurify on [jsdom](https://github.com/jsdom/jsdom). Older Node versions are known to work as well, but hey... no guarantees.
DOMPurify is written by security people who have vast background in web attacks and XSS. Fear not. For more details please also read about our [Security Goals & Threat Model](https://github.com/cure53/DOMPurify/wiki/Security-Goals-&-Threat-Model). Please, read it. Like, really.
## What does it do?
DOMPurify sanitizes HTML and prevents XSS attacks. You can feed DOMPurify with string full of dirty HTML and it will return a string (unless configured otherwise) with clean HTML. DOMPurify will strip out everything that contains dangerous HTML and thereby prevent XSS attacks and other nastiness. It's also damn bloody fast. We use the technologies the browser provides and turn them into an XSS filter. The faster your browser, the faster DOMPurify will be.
## How do I use it?
It's easy. Just include DOMPurify on your website.
### Using the unminified version (source-map available)
```html
<script type="text/javascript" src="dist/purify.js"></script>
```
### Using the minified and tested production version (source-map available)
```html
<script type="text/javascript" src="dist/purify.min.js"></script>
```
Afterwards you can sanitize strings by executing the following code:
```js
const clean = DOMPurify.sanitize(dirty);
```
Or maybe this, if you love working with Angular or alike:
```js
import DOMPurify from 'dompurify';
const clean = DOMPurify.sanitize('<b>hello there</b>');
```
The resulting HTML can be written into a DOM element using `innerHTML` or the DOM using `document.write()`. That is fully up to you.
Note that by default, we permit HTML, SVG **and** MathML. If you only need HTML, which might be a very common use-case, you can easily set that up as well:
```js
const clean = DOMPurify.sanitize(dirty, { USE_PROFILES: { html: true } });
```
### Is there any foot-gun potential?
Well, please note, if you _first_ sanitize HTML and then modify it _afterwards_, you might easily **void the effects of sanitization**. If you feed the sanitized markup to another library _after_ sanitization, please be certain that the library doesn't mess around with the HTML on its own.
### Okay, makes sense, let's move on
After sanitizing your markup, you can also have a look at the property `DOMPurify.removed` and find out, what elements and attributes were thrown out. Please **do not use** this property for making any security critical decisions. This is just a little helper for curious minds.
### Running DOMPurify on the server
DOMPurify technically also works server-side with Node.js. Our support strives to follow the [Node.js release cycle](https://nodejs.org/en/about/previous-releases).
Running DOMPurify on the server requires a DOM to be present, which is probably no surprise. Usually, [jsdom](https://github.com/jsdom/jsdom) is the tool of choice and we **strongly recommend** to use the latest version of _jsdom_.
Why? Because older versions of _jsdom_ are known to be buggy in ways that result in XSS _even if_ DOMPurify does everything 100% correctly. There are **known attack vectors** in, e.g. _jsdom v19.0.0_ that are fixed in _jsdom v20.0.0_ - and we really recommend to keep _jsdom_ up to date because of that.
Please also be aware that tools like [happy-dom](https://github.com/capricorn86/happy-dom) exist but **are not considered safe** at this point. Combining DOMPurify with _happy-dom_ is currently not recommended and will likely lead to XSS.
Other than that, you are fine to use DOMPurify on the server. Probably. This really depends on _jsdom_ or whatever DOM you utilize server-side. If you can live with that, this is how you get it to work:
```bash
npm install dompurify
npm install jsdom
```
For _jsdom_ (please use an up-to-date version), this should do the trick:
```js
const createDOMPurify = require('dompurify');
const { JSDOM } = require('jsdom');
const window = new JSDOM('').window;
const DOMPurify = createDOMPurify(window);
const clean = DOMPurify.sanitize('<b>hello there</b>');
```
Or even this, if you prefer working with imports:
```js
import { JSDOM } from 'jsdom';
import DOMPurify from 'dompurify';
const window = new JSDOM('').window;
const purify = DOMPurify(window);
const clean = purify.sanitize('<b>hello there</b>');
```
If you have problems making it work in your specific setup, consider looking at the amazing [isomorphic-dompurify](https://github.com/kkomelin/isomorphic-dompurify) project which solves lots of problems people might run into.
```bash
npm install isomorphic-dompurify
```
```js
import DOMPurify from 'isomorphic-dompurify';
const clean = DOMPurify.sanitize('<s>hello</s>');
```
## Is there a demo?
Of course there is a demo! [Play with DOMPurify](https://cure53.de/purify)
## What if I find a _security_ bug?
First of all, please immediately contact us via [email](mailto:mario@cure53.de) so we can work on a fix. [PGP key](https://keyserver.ubuntu.com/pks/lookup?op=vindex&search=0xC26C858090F70ADA)
Also, you probably qualify for a bug bounty! The fine folks over at [Fastmail](https://www.fastmail.com/) use DOMPurify for their services and added our library to their bug bounty scope. So, if you find a way to bypass or weaken DOMPurify, please also have a look at their website and the [bug bounty info](https://www.fastmail.com/about/bugbounty/).
## Some purification samples please?
How does purified markup look like? Well, [the demo](https://cure53.de/purify) shows it for a big bunch of nasty elements. But let's also show some smaller examples!
```js
DOMPurify.sanitize('<img src=x onerror=alert(1)//>'); // becomes <img src="x">
DOMPurify.sanitize('<svg><g/onload=alert(2)//<p>'); // becomes <svg><g></g></svg>
DOMPurify.sanitize('<p>abc<iframe//src=jAva	script:alert(3)>def</p>'); // becomes <p>abc</p>
DOMPurify.sanitize('<math><mi//xlink:href="data:x,<script>alert(4)</script>">'); // becomes <math><mi></mi></math>
DOMPurify.sanitize('<TABLE><tr><td>HELLO</tr></TABL>'); // becomes <table><tbody><tr><td>HELLO</td></tr></tbody></table>
DOMPurify.sanitize('<UL><li><A HREF=//google.com>click</UL>'); // becomes <ul><li><a href="//google.com">click</a></li></ul>
```
## What is supported?
DOMPurify currently supports HTML5, SVG and MathML. DOMPurify per default allows CSS, HTML custom data attributes. DOMPurify also supports the Shadow DOM - and sanitizes DOM templates recursively. DOMPurify also allows you to sanitize HTML for being used with the jQuery `$()` and `elm.html()` API without any known problems.
## What about legacy browsers like Internet Explorer?
DOMPurify does nothing at all. It simply returns exactly the string that you fed it. DOMPurify exposes a property called `isSupported`, which tells you whether it will be able to do its job, so you can come up with your own backup plan.
## What about DOMPurify and Trusted Types?
In version 1.0.9, support for [Trusted Types API](https://github.com/w3c/webappsec-trusted-types) was added to DOMPurify.
In version 2.0.0, a config flag was added to control DOMPurify's behavior regarding this.
When `DOMPurify.sanitize` is used in an environment where the Trusted Types API is available and `RETURN_TRUSTED_TYPE` is set to `true`, it tries to return a `TrustedHTML` value instead of a string (the behavior for `RETURN_DOM` and `RETURN_DOM_FRAGMENT` config options does not change).
Note that in order to create a policy in `trustedTypes` using DOMPurify, `RETURN_TRUSTED_TYPE: false` is required, as `createHTML` expects a normal string, not `TrustedHTML`. The example below shows this.
```js
window.trustedTypes!.createPolicy('default', {
createHTML: (to_escape) =>
DOMPurify.sanitize(to_escape, { RETURN_TRUSTED_TYPE: false }),
});
```
## Can I configure DOMPurify?
Yes. The included default configuration values are pretty good already - but you can of course override them. Check out the [`/demos`](https://github.com/cure53/DOMPurify/tree/main/demos) folder to see a bunch of examples on how you can [customize DOMPurify](https://github.com/cure53/DOMPurify/tree/main/demos#what-is-this).
### General settings
```js
// strip {{ ... }}, ${ ... } and <% ... %> to make output safe for template systems
// be careful please, this mode is not recommended for production usage.
// allowing template parsing in user-controlled HTML is not advised at all.
// only use this mode if there is really no alternative.
const clean = DOMPurify.sanitize(dirty, {SAFE_FOR_TEMPLATES: true});
// change how e.g. comments containing risky HTML characters are treated.
// be very careful, this setting should only be set to `false` if you really only handle
// HTML and nothing else, no SVG, MathML or the like.
// Otherwise, changing from `true` to `false` will lead to XSS in this or some other way.
const clean = DOMPurify.sanitize(dirty, {SAFE_FOR_XML: false});
```
### Control our allow-lists and block-lists
```js
// allow only <b> elements, very strict
const clean = DOMPurify.sanitize(dirty, {ALLOWED_TAGS: ['b']});
// allow only <b> and <q> with style attributes
const clean = DOMPurify.sanitize(dirty, {ALLOWED_TAGS: ['b', 'q'], ALLOWED_ATTR: ['style']});
// allow all safe HTML elements but neither SVG nor MathML
// note that the USE_PROFILES setting will override the ALLOWED_TAGS setting
// so don't use them together
const clean = DOMPurify.sanitize(dirty, {USE_PROFILES: {html: true}});
// allow all safe SVG elements and SVG Filters, no HTML or MathML
const clean = DOMPurify.sanitize(dirty, {USE_PROFILES: {svg: true, svgFilters: true}});
// allow all safe MathML elements and SVG, but no SVG Filters
const clean = DOMPurify.sanitize(dirty, {USE_PROFILES: {mathMl: true, svg: true}});
// change the default namespace from HTML to something different
const clean = DOMPurify.sanitize(dirty, {NAMESPACE: 'http://www.w3.org/2000/svg'});
// leave all safe HTML as it is and add <style> elements to block-list
const clean = DOMPurify.sanitize(dirty, {FORBID_TAGS: ['style']});
// leave all safe HTML as it is and add style attributes to block-list
const clean = DOMPurify.sanitize(dirty, {FORBID_ATTR: ['style']});
// extend the existing array of allowed tags and add <my-tag> to allow-list
const clean = DOMPurify.sanitize(dirty, {ADD_TAGS: ['my-tag']});
// extend the existing array of allowed attributes and add my-attr to allow-list
const clean = DOMPurify.sanitize(dirty, {ADD_ATTR: ['my-attr']});
// use functions to control which additional tags and attributes are allowed
const allowlist = {
'one': ['attribute-one'],
'two': ['attribute-two']
};
const clean = DOMPurify.sanitize(
'<one attribute-one="1" attribute-two="2"></one><two attribute-one="1" attribute-two="2"></two>',
{
ADD_TAGS: (tagName) => {
return Object.keys(allowlist).includes(tagName);
},
ADD_ATTR: (attributeName, tagName) => {
return allowlist[tagName]?.includes(attributeName) || false;
}
}
); // <one attribute-one="1"></one><two attribute-two="2"></two>
// prohibit ARIA attributes, leave other safe HTML as is (default is true)
const clean = DOMPurify.sanitize(dirty, {ALLOW_ARIA_ATTR: false});
// prohibit HTML5 data attributes, leave other safe HTML as is (default is true)
const clean = DOMPurify.sanitize(dirty, {ALLOW_DATA_ATTR: false});
```
### Control behavior relating to Custom Elements
```js
// DOMPurify allows to define rules for Custom Elements. When using the CUSTOM_ELEMENT_HANDLING
// literal, it is possible to define exactly what elements you wish to allow (by default, none are allowed).
//
// The same goes for their attributes. By default, the built-in or configured allow.list is used.
//
// You can use a RegExp literal to specify what is allowed or a predicate, examples for both can be seen below.
// When using a predicate function for attributeNameCheck, it can optionally receive the tagName as a second parameter
// for more granular control over which attributes are allowed for specific elements.
// The default values are very restrictive to prevent accidental XSS bypasses. Handle with great care!
const clean = DOMPurify.sanitize(
'<foo-bar baz="foobar" forbidden="true"></foo-bar><div is="foo-baz"></div>',
{
CUSTOM_ELEMENT_HANDLING: {
tagNameCheck: null, // no custom elements are allowed
attributeNameCheck: null, // default / standard attribute allow-list is used
allowCustomizedBuiltInElements: false, // no customized built-ins allowed
},
}
); // <div is=""></div>
const clean = DOMPurify.sanitize(
'<foo-bar baz="foobar" forbidden="true"></foo-bar><div is="foo-baz"></div>',
{
CUSTOM_ELEMENT_HANDLING: {
tagNameCheck: /^foo-/, // allow all tags starting with "foo-"
attributeNameCheck: /baz/, // allow all attributes containing "baz"
allowCustomizedBuiltInElements: true, // customized built-ins are allowed
},
}
); // <foo-bar baz="foobar"></foo-bar><div is="foo-baz"></div>
const clean = DOMPurify.sanitize(
'<foo-bar baz="foobar" forbidden="true"></foo-bar><div is="foo-baz"></div>',
{
CUSTOM_ELEMENT_HANDLING: {
tagNameCheck: (tagName) => tagName.match(/^foo-/), // allow all tags starting with "foo-"
attributeNameCheck: (attr) => attr.match(/baz/), // allow all containing "baz"
allowCustomizedBuiltInElements: true, // allow customized built-ins
},
}
); // <foo-bar baz="foobar"></foo-bar><div is="foo-baz"></div>
// Example with attributeNameCheck receiving tagName as a second parameter
const clean = DOMPurify.sanitize(
'<element-one attribute-one="1" attribute-two="2"></element-one><element-two attribute-one="1" attribute-two="2"></element-two>',
{
CUSTOM_ELEMENT_HANDLING: {
tagNameCheck: (tagName) => tagName.match(/^element-(one|two)$/),
attributeNameCheck: (attr, tagName) => {
if (tagName === 'element-one') {
return ['attribute-one'].includes(attr);
} else if (tagName === 'element-two') {
return ['attribute-two'].includes(attr);
} else {
return false;
}
},
allowCustomizedBuiltInElements: false,
},
}
); // <element-one attribute-one="1"></element-one><element-two attribute-two="2"></element-two>
```
### Control behavior relating to URI values
```js
// extend the existing array of elements that can use Data URIs
const clean = DOMPurify.sanitize(dirty, {ADD_DATA_URI_TAGS: ['a', 'area']});
// extend the existing array of elements that are safe for URI-like values (be careful, XSS risk)
const clean = DOMPurify.sanitize(dirty, {ADD_URI_SAFE_ATTR: ['my-attr']});
```
### Control permitted attribute values
```js
// allow external protocol handlers in URL attributes (default is false, be careful, XSS risk)
// by default only http, https, ftp, ftps, tel, mailto, callto, sms, cid and xmpp are allowed.
const clean = DOMPurify.sanitize(dirty, {ALLOW_UNKNOWN_PROTOCOLS: true});
// allow specific protocols handlers in URL attributes via regex (default is false, be careful, XSS risk)
// by default only (protocol-)relative URLs, http, https, ftp, ftps, tel, mailto, callto, sms, cid, xmpp and matrix are allowed.
// Default RegExp: /^(?:(?:(?:f|ht)tps?|mailto|tel|callto|sms|cid|xmpp):|[^a-z]|[a-z+.\-]+(?:[^a-z+.\-:]|$))/i;
const clean = DOMPurify.sanitize(dirty, {ALLOWED_URI_REGEXP: /^(?:(?:(?:f|ht)tps?|mailto|tel|callto|sms|cid|xmpp|matrix):|[^a-z]|[a-z+.\-]+(?:[^a-z+.\-:]|$))/i});
```
### Influence the return-type
```js
// return a DOM HTMLBodyElement instead of an HTML string (default is false)
const clean = DOMPurify.sanitize(dirty, {RETURN_DOM: true});
// return a DOM DocumentFragment instead of an HTML string (default is false)
const clean = DOMPurify.sanitize(dirty, {RETURN_DOM_FRAGMENT: true});
// use the RETURN_TRUSTED_TYPE flag to turn on Trusted Types support if available
const clean = DOMPurify.sanitize(dirty, {RETURN_TRUSTED_TYPE: true}); // will return a TrustedHTML object instead of a string if possible
// use a provided Trusted Types policy
const clean = DOMPurify.sanitize(dirty, {
// supplied policy must define createHTML and createScriptURL
TRUSTED_TYPES_POLICY: trustedTypes.createPolicy({
createHTML(s) { return s},
createScriptURL(s) { return s},
})
});
```
### Influence how we sanitize
```js
// return entire document including <html> tags (default is false)
const clean = DOMPurify.sanitize(dirty, {WHOLE_DOCUMENT: true});
// disable DOM Clobbering protection on output (default is true, handle with care, minor XSS risks here)
const clean = DOMPurify.sanitize(dirty, {SANITIZE_DOM: false});
// enforce strict DOM Clobbering protection via namespace isolation (default is false)
// when enabled, isolates the namespace of named properties (i.e., `id` and `name` attributes)
// from JS variables by prefixing them with the string `user-content-`
const clean = DOMPurify.sanitize(dirty, {SANITIZE_NAMED_PROPS: true});
// keep an element's content when the element is removed (default is true)
const clean = DOMPurify.sanitize(dirty, {KEEP_CONTENT: false});
// glue elements like style, script or others to document.body and prevent unintuitive browser behavior in several edge-cases (default is false)
const clean = DOMPurify.sanitize(dirty, {FORCE_BODY: true});
// remove all <a> elements under <p> elements that are removed
const clean = DOMPurify.sanitize(dirty, {FORBID_CONTENTS: ['a'], FORBID_TAGS: ['p']});
// extend the default FORBID_CONTENTS list to also remove <a> elements under <p> elements
const clean = DOMPurify.sanitize(dirty, {ADD_FORBID_CONTENTS: ['a'], FORBID_TAGS: ['p']});
// change the parser type so sanitized data is treated as XML and not as HTML, which is the default
const clean = DOMPurify.sanitize(dirty, {PARSER_MEDIA_TYPE: 'application/xhtml+xml'});
```
### Influence where we sanitize
```js
// use the IN_PLACE mode to sanitize a node "in place", which is much faster depending on how you use DOMPurify
const dirty = document.createElement('a');
dirty.setAttribute('href', 'javascript:alert(1)');
const clean = DOMPurify.sanitize(dirty, {IN_PLACE: true}); // see https://github.com/cure53/DOMPurify/issues/288 for more info
```
There is even [more examples here](https://github.com/cure53/DOMPurify/tree/main/demos#what-is-this), showing how you can run, customize and configure DOMPurify to fit your needs.
## Persistent Configuration
Instead of repeatedly passing the same configuration to `DOMPurify.sanitize`, you can use the `DOMPurify.setConfig` method. Your configuration will persist until your next call to `DOMPurify.setConfig`, or until you invoke `DOMPurify.clearConfig` to reset it. Remember that there is only one active configuration, which means once it is set, all extra configuration parameters passed to `DOMPurify.sanitize` are ignored.
## Hooks
DOMPurify allows you to augment its functionality by attaching one or more functions with the `DOMPurify.addHook` method to one of the following hooks:
- `beforeSanitizeElements`
- `uponSanitizeElement` (No 's' - called for every element)
- `afterSanitizeElements`
- `beforeSanitizeAttributes`
- `uponSanitizeAttribute`
- `afterSanitizeAttributes`
- `beforeSanitizeShadowDOM`
- `uponSanitizeShadowNode`
- `afterSanitizeShadowDOM`
It passes the currently processed DOM node, when needed a literal with verified node and attribute data and the DOMPurify configuration to the callback. Check out the [MentalJS hook demo](https://github.com/cure53/DOMPurify/blob/main/demos/hooks-mentaljs-demo.html) to see how the API can be used nicely.
_Example_:
```js
DOMPurify.addHook(
'uponSanitizeAttribute',
function (currentNode, hookEvent, config) {
// Do something with the current node
// You can also mutate hookEvent for current node (i.e. set hookEvent.forceKeepAttr = true)
// For other than 'uponSanitizeAttribute' hook types hookEvent equals to null
}
);
```
## Removed Configuration
| Option | Since | Note |
|-----------------|-------|--------------------------|
| SAFE_FOR_JQUERY | 2.1.0 | No replacement required. |
## Continuous Integration
We are currently using Github Actions in combination with BrowserStack. This gives us the possibility to confirm for each and every commit that all is going according to plan in all supported browsers. Check out the build logs here: https://github.com/cure53/DOMPurify/actions
You can further run local tests by executing `npm run test`.
All relevant commits will be signed with the key `0x24BB6BF4` for additional security (since 8th of April 2016).
### Development and contributing
#### Installation (`npm i`)
We support `npm` officially. GitHub Actions workflow is configured to install dependencies using `npm`. When using deprecated version of `npm` we can not fully ensure the versions of installed dependencies which might lead to unanticipated problems.
#### Scripts
We use ESLint as a pre-commit hook to ensure code consistency. Moreover, to ease formatting we use [prettier](https://github.com/prettier/prettier) while building the `/dist` assets happens through `rollup`.
These are our npm scripts:
- `npm run dev` to start building while watching sources for changes
- `npm run test` to run our test suite via jsdom and karma
- `test:jsdom` to only run tests through jsdom
- `test:karma` to only run tests through karma
- `npm run lint` to lint the sources using ESLint (via xo)
- `npm run format` to format our sources using prettier to ease to pass ESLint
- `npm run build` to build our distribution assets minified and unminified as a UMD module
- `npm run build:umd` to only build an unminified UMD module
- `npm run build:umd:min` to only build a minified UMD module
Note: all run scripts triggered via `npm run <script>`.
There are more npm scripts but they are mainly to integrate with CI or are meant to be "private" for instance to amend build distribution files with every commit.
## Security Mailing List
We maintain a mailing list that notifies whenever a security-critical release of DOMPurify was published. This means, if someone found a bypass and we fixed it with a release (which always happens when a bypass was found) a mail will go out to that list. This usually happens within minutes or few hours after learning about a bypass. The list can be subscribed to here:
[https://lists.ruhr-uni-bochum.de/mailman/listinfo/dompurify-security](https://lists.ruhr-uni-bochum.de/mailman/listinfo/dompurify-security)
Feature releases will not be announced to this list.

## What is this?
This is a collection of demos of how to use DOMPurify. When run without any additional configuration parameters, DOMPurify will reliably protect against XSS and DOM Clobbering attacks. But there is a lot of more things this library can do. For example proxy all HTTP resources, enhance accessibility, prevent links to open in the same window, allow and sand-box JavaScript and more.
This collection of demos shows to same code for several different ways you can use DOMPurify. Please feel free to suggest additional demos if needed. All demos we have collected so far will be shown and explained below.
### Basic Demo [Link](basic-demo.html)
This is the most basic of all demos. It shows how you user DOMPurify and that's it. No configuration, no hooks, no extras. Just DOMPurify running with default settings.
This is the relevant code:
```javascript
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty);
```
### Config Demo [Link](config-demo.html)
This demo shows how to use the configuration object the right way. In this demo, we only permit `<p>` elements and we want to preserve their text, but not the content of nested elements inside the `<p>`.
This is the relevant code:
```javascript
// Specify a configuration directive, only <P> elements allowed
// Note: We want to also keep <p>'s text content, so we add #text too
const config = { ALLOWED_TAGS: ['p', '#text'], KEEP_CONTENT: false };
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty, config);
```
### Advanced Config Demo [Link](advanced-config-demo.html)
This demo shows, how we can use the configuration object to instruct DOMPurify to be more specific with what is to be permitted and what is not. We want to permit `<p>` elements and the fictional `<ying>` and `<yang>` tag. We also want to allow the `kitty-litter` attribute because why not - and make sure that a `document`-object is returned after sanitation - and not a plain string.
This is the relevant code:
```javascript
// Specify a configuration directive
const config = {
ALLOWED_TAGS: ['p', '#text'], // only <P> and text nodes
KEEP_CONTENT: false, // remove content from non-allow-listed nodes too
ADD_ATTR: ['kitty-litter'], // permit kitty-litter attributes
ADD_TAGS: ['ying', 'yang'], // permit additional custom tags
RETURN_DOM: true, // return a document object instead of a string
};
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty, config);
```
### Hooks Demo [Link](hooks-demo.html)
DOMPurify allows you to use hooks. Hooks are basically scripts that can hook into certain parts of the DOMPurify code flow and do stuff. Stuff that you like to be done. By using hooks, you can literally make DOMPurify do whatever. To show you, how powerful and easy to use hooks are, we created some demos for you. Like this one, that essentially renders all tag content to be in capitals.
This is the relevant code:
```javascript
// Add a hook to convert all text to capitals
DOMPurify.addHook('beforeSanitizeAttributes', function (node) {
// Set text node content to uppercase
if (node.nodeName && node.nodeName === '#text') {
node.textContent = node.textContent.toUpperCase();
}
});
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty);
```
### Add hooks and remove hooks [Link](hooks-removal-demo.html)
A DOMPurify hook can also be removed in case you first need it and then you want to get rid of it right afterwards. This demo shows how you do that with ease and elegance.
This is the relevant code:
```javascript
// Add a hook to convert all text to capitals
DOMPurify.addHook('beforeSanitizeAttributes', function (node) {
// Set text node content to uppercase
if (node.nodeName && node.nodeName === '#text') {
node.textContent = node.textContent.toUpperCase();
}
});
// Clean HTML string and write into our DIV
let clean = DOMPurify.sanitize(dirty);
// now let's remove the hook again
console.log(DOMPurify.removeHook('beforeSanitizeAttributes'));
// Clean HTML string and write into our DIV
let clean = DOMPurify.sanitize(dirty);
```
### Hook to open all links in a new window [Link](hooks-target-blank-demo.html)
This hook is an important one and used quite commonly. It is made to assure that all elements that can function as a link will open the linked page in a new tab or window. This is often of great importance in web mailers and other tools, where a click on a link is not supposed to navigate the original page but rather open another window or tab.
This is the relevant code:
```javascript
// Add a hook to make all links open a new window
DOMPurify.addHook('afterSanitizeAttributes', function (node) {
// set all elements owning target to target=_blank
if ('target' in node) {
node.setAttribute('target', '_blank');
}
// set non-HTML/MathML links to xlink:show=new
if (
!node.hasAttribute('target') &&
(node.hasAttribute('xlink:href') || node.hasAttribute('href'))
) {
node.setAttribute('xlink:show', 'new');
}
});
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty);
```
### Hook to white-list safe URI Schemes [Link](hooks-scheme-allowlist.html)
Depending on where you show your sanitized HTML, different URI schemes might cause trouble. And in most situations, you only want to allow HTTP and HTTPS - but not any of those fancy URI schemes supported on mobile devices or even on the desktop with Windows 10. This hook demo shows how to easily make sure only HTTP, HTTPS and FTP URIs are permitted while all others are eliminated for good.
Note that you might want to be more thorough, if not only links but also backgrounds and other attributes should be covered. We have an example later on to [cover all these too](hooks-proxy-demo.html).
This is the relevant code:
```javascript
// allowed URI schemes
const allowlist = ['http', 'https', 'ftp'];
// build fitting regex
const regex = RegExp('^(' + allowlist.join('|') + '):', 'gim');
// Add a hook to enforce URI scheme allow-list
DOMPurify.addHook('afterSanitizeAttributes', function (node) {
// build an anchor to map URLs to
const anchor = document.createElement('a');
// check all href attributes for validity
if (node.hasAttribute('href')) {
anchor.href = node.getAttribute('href');
if (anchor.protocol && !anchor.protocol.match(regex)) {
node.removeAttribute('href');
}
}
// check all action attributes for validity
if (node.hasAttribute('action')) {
anchor.href = node.getAttribute('action');
if (anchor.protocol && !anchor.protocol.match(regex)) {
node.removeAttribute('action');
}
}
// check all xlink:href attributes for validity
if (node.hasAttribute('xlink:href')) {
anchor.href = node.getAttribute('xlink:href');
if (anchor.protocol && !anchor.protocol.match(regex)) {
node.removeAttribute('xlink:href');
}
}
});
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty);
```
### Hook to allow and sand-box all JavaScript [Link](hooks-mentaljs-demo.html)
Okay, now this is real witch-craft! Imagine you want users to submit JavaScript but it should be sand-boxed. With a hook, you can actually do that. What we are doing here is permitting all JavaScript and event handlers, but take their contents and sand-box it using Gareth Heyes' amazing [MentalJS](https://github.com/hackvertor/MentalJS) library. The hook shows how do to this safely.
Be careful though, this is playing with fire. If you want to use this in production, better give us a quick ping to see if all is really working as desired.
This is the relevant code:
```javascript
// allow script elements
const config = {
ADD_TAGS: ['script'],
ADD_ATTR: ['onclick', 'onmouseover', 'onload', 'onunload'],
};
// Add a hook to sanitize all script content with MentalJS
DOMPurify.addHook('uponSanitizeElement', function (node, data) {
if (data.tagName === 'script') {
let script = node.textContent;
if (
!script ||
'src' in node.attributes ||
'href' in node.attributes ||
'xlink:href' in node.attributes
) {
return node.parentNode.removeChild(node);
}
try {
let mental = MentalJS().parse({
options: {
eval: false,
dom: true,
},
code: script,
});
return (node.textContent = mental);
} catch (e) {
return node.parentNode.removeChild(node);
}
}
});
// Add a hook to sanitize all white-listed events with MentalJS
DOMPurify.addHook('uponSanitizeAttribute', function (node, data) {
if (data.attrName.match(/^on\w+/)) {
let script = data.attrValue;
try {
return (data.attrValue = MentalJS().parse({
options: {
eval: false,
dom: true,
},
code: script,
}));
} catch (e) {
return (data.attrValue = '');
}
}
});
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty, config);
```
### Hook to proxy all links [Link](hooks-link-proxy-demo.html)
DOMPurify itself permits links to all resources that don't cause XSS. That includes pretty much all URI schemes and of course HTTP and HTTPS links. Yet, often, preventing XSS is not everything you want to do. And a common use case for a sanitizer is to also proxy all existing links on a website to make sure a de-referrer is used or the website owner has more control over what links are pointing where - to avoid referrer leaks, attacks using window.opener and alike. This hook shows, how all out-bound links can easily be proxied for maximum safety.
This is the relevant code:
```javascript
// Add a hook to make all links point to a proxy
DOMPurify.addHook('afterSanitizeAttributes', function (node) {
// proxy form actions
if ('action' in node) {
node.setAttribute(
'action',
proxy + encodeURIComponent(node.getAttribute('action'))
);
}
// proxy regular HTML links
if (node.hasAttribute('href')) {
node.setAttribute(
'href',
proxy + encodeURIComponent(node.getAttribute('href'))
);
}
// proxy SVG/MathML links
if (node.hasAttribute('xlink:href')) {
node.setAttribute(
'xlink:href',
proxy + encodeURIComponent(node.getAttribute('xlink:href'))
);
}
});
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty);
```
### Hook to proxy all HTTP leaks including CSS [Link](hooks-proxy-demo.html)
Now this is a hook you don't talk about on your first date. This monster has the purpose of proxying **all** known [HTTP leaks](https://github.com/cure53/HTTPLeaks) including the ones hidden in CSS. It proxies HTML, CSS rules, in-line styles, `@media` rules, `@font-face` rules and `@keyframes`. It further eliminates `@charset` and `@import` as they both help carrying out XSS attacks. This hook is supposed to be a comprehensive demo on how to cover each and every HTTP leak. That's why the amount of code is a bit higher than usual.
When ever you want to reliably filter HTML and CSS using DOMPurify, this is the way to go. How to try the demo? Run the HTML file linked above in your browser and have a look at the network tab of your favorite debugger. You will see that all external resources are proxied. If not then you found a bug.
This is the relevant code:
```javascript
// Specify proxy URL
const proxy = 'https://my.proxy/?url=';
// What do we allow? Not much for now. But it's tight.
const config = {
FORBID_TAGS: ['svg'],
WHOLE_DOCUMENT: true,
};
// Specify attributes to proxy
const attributes = ['action', 'background', 'href', 'poster', 'src', 'srcset']
// specify the regex to detect external content
const regex = /(url\("?)(?!data:)/gim;
/**
* Take CSS property-value pairs and proxy URLs in values,
* then add the styles to an array of property-value pairs
*/
function addStyles(output, styles) {
for (let prop = styles.length - 1; prop >= 0; prop--) {
if (styles[styles[prop]]) {
let url = styles[styles[prop]].replace(regex, '$1' + proxy);
styles[styles[prop]] = url;
}
if (styles[styles[prop]]) {
output.push(styles[prop] + ':' + styles[styles[prop]] + ';');
}
}
}
/**
* Take CSS rules and analyze them, proxy URLs via addStyles(),
* then create matching CSS text for later application to the DOM
*/
function addCSSRules(output, cssRules) {
for (let index = cssRules.length - 1; index >= 0; index--) {
let rule = cssRules[index];
// check for rules with selector
if (rule.type == 1 && rule.selectorText) {
output.push(rule.selectorText + '{');
if (rule.style) {
addStyles(output, rule.style);
}
output.push('}');
// check for @media rules
} else if (rule.type === rule.MEDIA_RULE) {
output.push('@media ' + rule.media.mediaText + '{');
addCSSRules(output, rule.cssRules);
output.push('}');
// check for @font-face rules
} else if (rule.type === rule.FONT_FACE_RULE) {
output.push('@font-face {');
if (rule.style) {
addStyles(output, rule.style);
}
output.push('}');
// check for @keyframes rules
} else if (rule.type === rule.KEYFRAMES_RULE) {
output.push('@keyframes ' + rule.name + '{');
for (let i = rule.cssRules.length - 1; i >= 0; i--) {
let frame = rule.cssRules[i];
if (frame.type === 8 && frame.keyText) {
output.push(frame.keyText + '{');
if (frame.style) {
addStyles(output, frame.style);
}
output.push('}');
}
}
output.push('}');
}
}
}
/**
* Proxy a URL in case it's not a Data URI
*/
function proxyAttribute(url) {
if (/^data:image\//.test(url)) {
return url;
} else {
return proxy + escape(url);
}
}
// Add a hook to enforce proxy for leaky CSS rules
DOMPurify.addHook('uponSanitizeElement', function (node, data) {
if (data.tagName === 'style') {
let output = [];
addCSSRules(output, node.sheet.cssRules);
node.textContent = output.join('\n');
}
});
// Add a hook to enforce proxy for all HTTP leaks incl. inline CSS
DOMPurify.addHook('afterSanitizeAttributes', function (node) {
// Check all src attributes and proxy them
for (let i = 0; i <= attributes.length - 1; i++) {
if (node.hasAttribute(attributes[i])) {
node.setAttribute(
attributes[i],
proxyAttribute(node.getAttribute(attributes[i]))
);
}
}
// Check all style attribute values and proxy them
if (node.hasAttribute('style')) {
let styles = node.style;
let output = [];
for (let prop = styles.length - 1; prop >= 0; prop--) {
// we re-write each property-value pair to remove invalid CSS
if (node.style[styles[prop]] && regex.test(node.style[styles[prop]])) {
let url = node.style[styles[prop]].replace(regex, '$1' + proxy);
node.style[styles[prop]] = url;
}
output.push(styles[prop] + ':' + node.style[styles[prop]] + ';');
}
// re-add styles in case any are left
if (output.length) {
node.setAttribute('style', output.join(''));
} else {
node.removeAttribute('style');
}
}
});
// Clean HTML string and write into our DIV
const clean = DOMPurify.sanitize(dirty, config);
```
### Hook to sanitize SVGs shown via an `<img>` tag. [Link](hooks-svg-demo.html)
DOMPurify can be used to sanitize SVGs, but there can be some issues with some of their content and that can be solved via custom hooks and parsing. Also, it's possible to allow some tags which are disabled by default when showing SVGs via an `<img>` tag.
Here is an example which works well for content generated by Illustrator:
```javascript
// Add a hook to post-process a sanitized SVG
DOMPurify.addHook('afterSanitizeAttributes', function (node) {
// Fix namespaces added by Adobe Illustrator
node.setAttribute('xmlns', 'http://www.w3.org/2000/svg');
node.setAttribute('xmlns:xlink', 'http://www.w3.org/1999/xlink');
});
// Clean SVG string and allow the "filter" tag
const clean = DOMPurify.sanitize(dirty, { ADD_TAGS: ['filter'] });
// Remove partial XML comment left in the HTML
let badTag = clean.indexOf(']>');
let pureSvg = clean.substring(badTag < 0 ? 0 : 5, clean.length);
// Show sanitized content in <img> element
let img = new Image();
img.src = 'data:image/svg+xml;base64,' + window.btoa(pureSvg);
document.getElementById('sanitized').appendChild(img);
```
