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:
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.
Potential XSS vulnerability in jQuery
In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing elements 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.
NOTE: Despite being a minor release, this update includes a breaking change that we had to make to fix a security issue ( CVE-2020-11022). Please follow the blog post & the upgrade guide for more details.
