SEVERITY
CVSS v3.x: 4.6 (Medium)
PATCHED VERSIONS
- >= 2.1.17
DESCRIPTION
Impact
The Trix editor, in versions prior to 2.1.17, is vulnerable to XSS
attacks when a data-trix-serialized-attributes attribute bypasses
the DOMPurify sanitizer.
An attacker could craft HTML containing a data-trix-serialized-attributes
attribute with a malicious payload that, when the content is rendered,
could 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 2.1.17 or later.
