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-2025-48919
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 [3]

Reported By: 
* Pierre Rudloff (prudloff) [4]

Fixed By: 
* Norman Kämper-Leymann (norman.lol) [5]

Coordinated By: 
* Juraj Nemec (poker10) [6] of the Drupal Security Team
* Pierre Rudloff (prudloff) [7]
* Cathy Theys (yesct) [8] of the Drupal Security Team
