SCA: security update for wagtail (GHSA-p5cm-246w-84jm)

medium Tenable Self-Hosted Container Security Plugin ID 438272

Description

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

 - Wagtail is an open source content management system built on Django. Prior to versions 6.3.8, 7.0.6,
 7.2.3, and 7.3.1, a stored cross-site scripting (XSS) vulnerability exists on rendering TableBlock blocks
 within a StreamField. A user with access to create or edit pages containing TableBlock StreamField blocks
 is able to set specially-crafted class attributes on the block which run arbitrary JavaScript code when
 the page is viewed. When viewed by a user with higher privileges, this could lead to performing actions
 with that user's credentials. The vulnerability is not exploitable by an ordinary site visitor without
 access to the Wagtail admin, and only affects sites using TableBlock. This issue has been patched in
 versions 6.3.8, 7.0.6, 7.2.3, and 7.3.1. (CVE-2026-28222)
