Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-c2j3-45gr-mqc4. This link is maintained to preserve external references.
Original Description
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.
Correção
XSS
