node-dompurify: DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG
CVE-2026-49459 is fixed in node-dompurify on 1 platform by DEBIAN-CVE-2026-49459 (version 3.4.12+dfsg-1), released July 22, 2026. It is not reported as exploited. Patch Radar priority: Routine.
DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Prior to 3.4.6, DOMPurify.sanitize(root, { IN_PLACE: true }) could preserve event-handler attributes on an attacker-controlled <form> root when a descendant name clobbered properties checked by _isClobbered, because _forceRemove no-opped on the parent-less root and _sanitizeAttributes returned early. This issue is fixed in version 3.4.6.
