Project: Simple Klaro [1] Date: 2025-May-28 Security risk: *Moderately critical* 13 ∕ 25 AC:Complex/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Cross Site Scripting
Affected versions: <1.10.0 CVE IDs: CVE-2025-48918 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 mark its administrative permission as restricted, creating the possibility for the permission to be granted too broadly. A malicious admin could execute a Cross Site Scripting (XSS) attack.
This vulnerability is mitigated by the fact that an attacker must have a role with the "administer simple klaro" permission.
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 [3]
