NVD Description

Note: Versions mentioned in the description apply only to the upstream trigger-dev package and not the trigger-dev package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

DOMPurify before 3.4.11 fails to clone the ALLOWED_ATTR allowlist when setConfig() is used with an uponSanitizeAttribute hook, allowing the hook to permanently mutate the shared allowlist. Attackers can register a hook that conditionally allows dangerous attributes like onerror for trusted elements, then submit untrusted content that inherits the polluted allowlist and executes event handlers as stored XSS.
