Advisory ID: 
BACKDROP-SA-CONTRIB-2025-001
Security risk: 
Moderately Critical
Vulnerability: 
Cross Site Scripting
Versions affected: 
  • Google Tag module 1.x-1.x versions prior to 1.x-1.6.2.
Description: 

This module enables you to integrate the site with the Google Tag Manager (GTM) application.

The module doesn't have the "restrict access" flag on the "administer google_tag_container" permission. A user with this permission can load a GTM container that completely changes the page or inserts malicious JS, resulting in a cross site scripting vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with the aforementioned permission.

Solution: 

Upgrade your site to the most recent version of Google Tag manager. Download available on the Google Tag Manager module page.
