Description : Trix is a what-you-see-is-what-you-get rich text editor for everyday writing. Prior to 2. 1. 17, Trix is vulnerable to cross-site scripting when a data-trix-serialized-attributes attribute bypasses the DOMPurify sanitizer.
An attacker can craft HTML containing a data-trix-serialized-attributes attribute with a malicious payload that, when rendered, executes arbitrary JavaScript in the user's session and may perform unauthorized actions or disclose sensitive information. This issue is fixed in version 2. 1. 17.
Severity: 0.0
