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.

DOMPurify was [started in February 2014](https://github.com/cure53/DOMPurify/commit/a630922616927373485e0e787ab19e73e3691b2b) and, meanwhile, has reached version **v3.1.6**. + +DOMPurify is written in 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 v2.5.6](https://github.com/cure53/DOMPurify/releases/tag/2.5.6) 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 [19 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 v16.x, v17.x, v18.x and v19.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 development version + +```html + +``` + +### Using the minified and tested production version (source-map available) + +```html + +``` + +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('hello there'); +``` + +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 } }); +``` + +### Where are the TypeScript type definitions? + +They can be found here: [@types/dompurify](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/dompurify) + +### 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/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('hello there'); +``` + +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('hello there'); +``` + +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('hello'); +``` + +## 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(''); // becomes +DOMPurify.sanitize(''); // becomes +DOMPurify.sanitize('
