Details

Potential XSS vulnerability in jQuery ### Impact Passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. `.html()`, `.append()`, and others) may execute untrusted code. ### Patches This problem is patched in jQuery 3.5.0. ### Workarounds To workaround the issue without upgrading, adding the following to your code: ```js jQuery.htmlPrefilter = function( html ) { return html; }; ``` You need to use at least jQuery 1.12/2.2 or newer to be able to apply this workaround. ### References https://blog.jquery.com/2020/04/10/jquery-3-5-0-released/ https://jquery.com/upgrade-guide/3.5/ ### For more information If you have any questions or comments about this advisory, search for a relevant issue in [the jQuery repo](https://github.com/jquery/jquery/issues).
