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:
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.
