Description

DOMPurify before 3.4.13 contains a cross-site scripting vulnerability in IN_PLACE sanitization where element-removal hooks fail to neutralize detached subtrees. Attackers can supply HTML with event handlers on descendant elements that execute after sanitization completes, even though the returned root appears clean.
