DOMPurify: Trusted Types policy survives `clearConfig()` and can poison later `RETURN_TRUSTED_TYPE` output

Impact A DOMPurify instance that is reused across trust boundaries can stay bound to a previously supplied TRUSTEDTYPESPOLICY even after clearConfig is called. A later caller that requests RETURNTRUSTEDTYPE receives a TrustedHTML object created by the old policy, not by a clean default...

DOMPurify: SAFE_FOR_TEMPLATES bypass - template expressions survive sanitization inside <template> content when using DOM output modes

Summary When DOMPurify is configured with both SAFEFORTEMPLATES: true and RETURNDOM: true or INPLACE: true, an attacker can inject template expressions, such as $evil, evil, or , that survive the sanitization pass inside element content. This bypasses the explicit purpose of SAFEFORTEMPLATES, whi...

GHSA-RP9W-3FW7-7CWQ DOMPurify IN_PLACE Sanitization Bypass via Attached Shadow Root Inside <template>.content

If the HTML you give it contains a element, and inside that template there's an element with a shadow DOM attached to it, DOMPurify quietly skips over the shadow contents. Whatever the attacker put in there - an image with an onerror handler, a link with a javascript: URL, even a full script -...

GHSA-X4VX-RJVF-J5P4 DOMPurify: `IN_PLACE` mode trusts attacker-controlled `nodeName` on live non-form nodes, allowing script retention and XSS via attacker-supplied DOM objects

Summary When DOMPurify.sanitizeroot, INPLACE: true is called on an attacker-supplied live DOM node, DOMPurify still trusts currentNode.nodeName for non-form nodes in the main sanitizeElements pipeline. A real child node whose observable nodeName is attacker-controlled can therefore be misclassifi...
