Details

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.

Is GHSA-jpcq-cgw6-v4j6 in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected jquery, and gives you the command that fixes it.

Scan a project free, no signup Or connect GitHub to scan every repo
