Trix vulnerable to Cross-site Scripting on copy & paste

Impact

The Trix editor, in versions prior to 2.1.15, is vulnerable to XSS attacks when pasting malicious code.

An attacker could trick a user to copy and paste malicious code that would execute arbitrary JavaScript code within the context of the user's session, potentially leading to unauthorized actions being performed or sensitive information being disclosed.

Patches

Update Recommendation: Users should upgrade to Trix editor version 2.1.15 or later.
