CVE-2026-109345 is fixed in node-dompurify on 1 platform by DEBIAN-CVE-2026-109345 (version 3.4.16+dfsg-1), released October 13, 2026. It is not reported as exploited. Patch Radar priority: Routine.
DOMPurify before 3.4.16 contains a cross-site scripting vulnerability that allows attackers to bypass sanitization because IN_PLACE mode returns a force-removed style element whose text content still carries markup. Attackers can supply a style element containing a closing style tag and an img onerror payload, which executes script when the application serializes and re-parses the returned node.
