Summary

DOMPurify XSS via Missing Rawtext Elements in SAFE_FOR_XML

Description

DOMPurify 3.1.3 through 3.3.1 and 2.5.3 through 2.5.8, fixed in commit 2726c74, contain a cross-site scripting vulnerability that allows attackers to bypass attribute sanitization by exploiting five missing rawtext elements (noscript, xmp, noembed, noframes, iframe) in the SAFE_FOR_XML regex. Attackers can include payloads like in attribute values to execute JavaScript when sanitized output is placed inside these unprotected rawtext contexts.
