## Description

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.
