Anti-Spam: Spam Protection | Block Spam Users, Comments, Forms <= 2024.7 - Cross-Site Request Forgery to Multiple Administrative Actions

5.4
Cross-Site Request Forgery (CSRF)
CVE CVE-2025-2935
CVSS 5.4 (Medium)
Publicly Published June 5, 2025
Last Updated October 17, 2025
Researcher Noah Stead (TurtleBurg)

Description

The Anti-Spam: Spam Protection | Block Spam Users, Comments, Forms plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2024.7. This is due to missing or incorrect nonce validation in the 'ss_option_maint.php' and 'ss_user_filter_list' files. This makes it possible for unauthenticated attackers to delete pending comments, and re-enable a previously blocked user via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
