drupal/simple_klaro - SA-CONTRIB-2025-073
The "Simple Klaro" module adds the "Klaro! A Simple Consent Manager" to your website and allows you to configure it according to your needs in the Drupal backend.
The module doesn't sufficiently sanitise data attributes allowing persistent Cross Site Scripting (XSS) attacks.
This vulnerability is mitigated by the fact that an attacker must have a role with permission to enter HTML tags containing specific data attributes.
