Project: Anti-Spam by CleanTalk [1] Date: 2026-February-25 Security risk: *Moderately critical* 13 ∕ 25 AC:Complex/A:None/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2] Vulnerability: Cross-site scripting

Affected versions: <9.7.0 CVE IDs: CVE-2026-3213 Description:  This module enables you to block bots by Firewall.

The module doesn't sufficiently sanitize user input leading to a reflected Cross-site scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that the vulnerable functionality is only presented to users that are "challenged" or blocked by the firewall.

Solution:  Install the latest version:

* If you use the Anti-Spam by CleanTalk module for Drupal, upgrade to Anti-Spam by CleanTalk 9.7.0 [3].
