Until an official fix is released, restrict access to the affected plugin and monitor for suspicious activity. Avoid installing untrusted plugins and consider disabling the CleanTalk plugin if feasible. Follow vendor updates closely for an official patch or temporary mitigation.

Description

The Spam protection, Anti-Spam, FireWall by CleanTalk plugin for WordPress is vulnerable to unauthorized Arbitrary Plugin Installation due to an authorization bypass via reverse DNS spoofing on the checkWithoutToken function in all versions up to, and including, 6.43.2. This makes it possible for unauthenticated attackers to install and activate arbitrary plugins which can be leveraged to achieve remote code execution if another vulnerable plugin is installed and activated.
