Impact
Passing HTML containing <option> elements from untrusted sources - even after sanitizing them - 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 this issue without upgrading, use DOMPurify with its SAFE_FOR_JQUERY option to sanitize the HTML string before passing it to a jQuery method.
