NVD Description

Note: Versions mentioned in the description apply only to the upstream awx package and not the awx package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

DOMPurify before 3.4.12 fails to execute afterSanitizeElements hook for custom elements allowed via CUSTOM_ELEMENT_HANDLING.tagNameCheck, allowing attributes to bypass application security policies. Attackers can preserve sensitive attributes on custom elements that later re-inject them into innerHTML sinks, creating second-order XSS gadgets.
