SCA: security update for actionview (GHSA-v55j-83pf-r9cq)

low Tenable Self-Hosted Container Security Plugin ID 439115

Description

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

 - Action View provides conventions and helpers for building web pages with the Rails framework. Prior to
 versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when a blank string is used as an HTML attribute name in Action
 View tag helpers, the attribute escaping is bypassed, producing malformed HTML. A carefully crafted
 attribute value could then be misinterpreted by the browser as a separate attribute name, possibly leading
 to XSS. Applications that allow users to specify custom HTML attributes are affected. Versions 8.1.2.1,
 8.0.4.1, and 7.2.3.1 contain a patch. (CVE-2026-33168)

Solution

Update the actionview library and its related packages to version 7.2.3.1 or later.
