Google Tag - Moderately critical - Cross Site Scripting - SA-CONTRIB-2025-011

Project: Google TagDate: 2025-January-29Security risk: Moderately critical 13 ∕ 25 AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:AllVulnerability: Cross Site ScriptingAffected versions: <1.8.0 || >=2.0.0 <2.0.8Description: 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: Install the latest version:

• If you use the Google Tag module 8.x, upgrade to Google Tag 8.x-1.8
• If you use the Google Tag module 2.0.x, upgrade to Google Tag 2.0.8
