Trix: Stored XSS vulnerability through serialized attributes

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

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.

### 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. ### References The XSS vulnerability was responsibly reported by Hackerone researcher [newbiefromcoma](https://hackerone.com/newbiefromcoma).
