AI-suggested
Upgrade the 'highlight_js' module to version 1.3.1 or later, where the vulnerability has been fixed. No other mitigation steps are indicated.
Description
The Drupal module 'highlight_js' allows adding syntax-highlighted code snippets using CKEditor 5. Versions prior to 1.3.1 do not properly validate input to the CKEditor 5 preview endpoint, resulting in a reflected cross-site scripting (XSS) vulnerability. This flaw was fixed in version 1.3.1.
