| Doc Text: |
A flaw was found in Trix, a rich text editor. An attacker can exploit a cross-site scripting (XSS) vulnerability by crafting malicious HTML with a `data-trix-serialized-attributes` attribute. This attribute can bypass the DOMPurify sanitizer, allowing the execution of arbitrary JavaScript in a user's session. This could lead to unauthorized actions or the disclosure of sensitive information.
