Vulnerability:
Cross Site Scripting
Affected versions:
<1.10.0
CVE IDs:
CVE-2025-48919
Description:
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.
Solution:
Install the latest version:
- If you use the "Simple Klaro" module for Drupal 9.x/10.x/11.x, upgrade to Simple Klaro 1.10.0
