SCA: security update for action_text-trix, trix (GHSA-53g2-mvcc-q9x3)

medium Tenable Self-Hosted Container Security Plugin ID 445283

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 stored cross-site scripting when crafted HTML is pasted into the editor. HTMLParser
 processes a mock attachment in a `<span>` with an empty `data-trix-attachment="{}"` value, causing data-
 trix-attributes to be applied to a plain string piece. StringPiece.fromJSON accepts an unvalidated href,
 allowing a javascript: URI to enter the document model and serialized HTML and execute when another user
 renders and clicks the content. Applications that apply server-side HTML sanitization can neutralize the
 payload on save. This issue is fixed in version 2.1.18. (CVE-2026-73428)

Solution

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