Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. 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.
This CVE is for a different package in a different ecosystem that happens to share a similar name
Reopening: closed in error by my triage tooling as a cross-ecosystem false positive. Re-triaging.
This CVE is in a JavaScript/NodeJS package; the JavaScript here is not shipped in the binary RPMs.
