Cross Site Scripting
Versions affected: 
  • EU Cookie Compliance 1.x-2.x.x versions prior to 2.26.0

This module addresses the General Data Protection Regulation (GDPR) that came into effect 25th May 2018, and the EU Directive on Privacy and Electronic Communications from 2012. It provides a banner where you can gather consent from the user when the website stores cookies on their computer or otherwise handles their personal information.

The module doesn't sufficiently sanitize data for some interface labels and strings shown in the cookie policy banner, opening up possibility of Cross Site Scripting exploits that can be created by somebody that has access to the admin interface of the module.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Administer EU Cookie Compliance banner".


Upgrade your site to the most recent version of EU Cookie Compliance.  Download available on the EU Cookie Compliance 2.26.0 release page. See the update instructions, if needed.
