CVE-2026-65912 is fixed in node-dompurify on 1 platform by DEBIAN-CVE-2026-65912 (version 3.3.2+dfsg-1), released July 24, 2026. It is not reported as exploited. Patch Radar priority: Routine.
DOMPurify before 3.3.2 contains a URI validation bypass vulnerability when ADD_ATTR is provided as a predicate function via EXTRA_ELEMENT_HANDLING.attributeCheck. Attackers can supply a predicate that accepts specific attribute and tag combinations to bypass URI-safe validation, allowing unsafe protocols like javascript: to survive sanitization and execute as DOM-based XSS when the link is activated.
