Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows attackers to inject and execute malicious JavaScript code by exploiting a flaw in how certain text areas are sanitized, specifically by using closing tags to break out of safe text contexts. It affects specific versions of the DOMPurify library, and while the issue has been fixed in the latest version, older versions remain vulnerable and unpatched.

Technical Description

DOMPurify 3.1.3 through 3.2.6 and 2.5.3 through 2.5.8 contain a cross-site scripting vulnerability that allows attackers to bypass attribute sanitization by exploiting missing textarea rawtext element validation in the SAFE_FOR_XML regex. Attackers can include closing rawtext tags like </textarea> in attribute values to break out of rawtext contexts and execute JavaScript when sanitized output is placed inside rawtext elements. The 3.x branch was fixed in 3.2.7; the 2.x branch was never patched.
