Project: Klaro Cookie & Consent Management [1]
Date: 2025-June-25
Security risk: *Moderately critical* 14 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross-site Scripting
Affected versions: <3.0.7
CVE IDs: CVE-2025-5682
Description:
Klaro Cookie & Consent Management module is used for consent management for
cookies and external sources. It makes changes to the markup to enable or
disable loading.
The module doesn't sufficiently sanitize some HTML 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 attributes.
Solution:
Install the latest version:
* If you use the Klaro Cookie & Consent Management module for Drupal
10.x/11.x, upgrade to Klaro Cookie & Consent Management 3.0.7 [3]
