Hi,

The following vulnerability was published for node-dompurify.

CVE-2026-65901[0]:
| DOMPurify through 3.4.6 contains a cross-site scripting
| vulnerability in IN_PLACE mode that trusts attacker-controlled
| nodeName on live non-form nodes. Attackers can supply hostile live
| DOM objects with real script children whose observable nodeName is
| clobbered to appear as allowed elements, causing scripts to execute
| when the sanitized tree is inserted into a live document.

Can you please check if and where this has been fixed? The GHSA is not
fully clear about that.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
