SCA: security update for action_text-trix, trix (GHSA-53p3-c7vp-4mcc)

low Tenable Self-Hosted Container Security Plugin ID 439436

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Trix is a what-you-see-is-what-you-get rich text editor for everyday writing. Prior to 2.1.18, Trix is
 vulnerable to cross-site scripting when a crafted application/x-trix-document JSON payload is dropped into
 an editor using the fallback Level0InputController, such as an embedded WebView without Input Events Level
 2 support. The StringPiece.fromJSON method trusts href attributes from the JSON payload without
 sanitization, allowing a draggable element containing a javascript: URI to bypass DOMPurify sanitization
 and inject executable JavaScript into the DOM. Exploitation requires the victim to drag and drop attacker-
 controlled content, and server-side HTML sanitization can neutralize the payload on save. This issue is
 fixed in version 2.1.18. (CVE-2026-73427)

Solution

Update the action_text-trix library and its related packages to version 2.1.18 or later.
