CVE-2026-65899 is fixed in node-dompurify on 1 platform by DEBIAN-CVE-2026-65899 (version 3.4.12+dfsg-1), released July 24, 2026. It is not reported as exploited. Patch Radar priority: Routine.
DOMPurify 3.0.0 before 3.4.9 does not reset the retained Trusted Types policy when clearConfig() is called, so a DOMPurify instance reused across trust boundaries stays bound to a previously supplied TRUSTED_TYPES_POLICY. A later caller that requests RETURN_TRUSTED_TYPE output receives a TrustedHTML object created by the old (potentially unsafe) policy rather than a clean default, which can lead to script execution at a Trusted Types sink. Passing TRUSTED_TYPES_POLICY: null on the later call also does not clear the retained policy.
