Potential XSS vulnerability in jQuery

CVE-2020-11023 — CVSS 6.9/10. Fix: upgrade to 3.5.0.

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](https://github.com/cure53/DOMPurify) with its `SAFE_FOR_JQUERY` option to sanitize the HTML string before passing it to a jQuery method.
