Name of the Vulnerable Software and Affected Versions DOMPurify versions prior to 3.4.7
Description A cross-site scripting issue exists when using IN PLACE mode. The software trusts the nodeName of live non-form nodes, which can be controlled by an attacker. By providing hostile live DOM objects with script children and clobbering the nodeName to mimic allowed elements, an attacker can execute scripts when the sanitized tree is inserted into a live document.
Recommendations Update to version 3.4.7 or later.
