CVE-2026-116803 is fixed in node-dompurify on 1 platform by DEBIAN-CVE-2026-116803 (version 3.4.17+dfsg-1), released November 3, 2026. It is not reported as exploited. Patch Radar priority: Routine.
DOMPurify before 3.4.17 contains a cross-site scripting vulnerability that allows attackers to keep event handlers armed when an IN_PLACE hook removes a parent or sibling node. Attacker markup in detached subtrees is never walked or neutralized, so handlers like img onerror fire after sanitize() returns, causing DOM XSS.
