A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the WordPress BSK Forms Blacklist plugin, specifically in versions through 3.9. This vulnerability allows for Blind SQL Injection. The issue arises because the plugin does not properly validate requests, enabling attackers to trick users with higher privileges into performing actions that could manipulate the database.

Impact

Exploitation of this vulnerability could allow attackers to perform unauthorized actions on behalf of users with higher privileges, potentially leading to Blind SQL Injection, where an attacker can manipulate database queries without directly seeing the results.

Remediation

Users of the BSK Forms Blacklist WordPress plugin should update to version 4.0 or later to address this vulnerability. Patchstack users can enable auto-update for vulnerable plugins.
