Advisory ID: 
BACKDROP-SA-CONTRIB-2025-010
Security risk: 
Moderately Critical
Vulnerability: 
Cross Site Scripting
Versions affected: 
  • GDPR cookies versions prior to 1.x-1.3.4
Description: 

The GDPR cookies module enables sites to comply with the European cookie law using tarteaucitron.js.

The module doesn't sufficiently filter user-supplied markup inside of content leading to a persistent Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have permission to insert specific data attributes.

Solution: 

Upgrade your site to the most recent version of GDPR Cookies module.
