CVE-2024-10781 Information

Description

The Spam protection Anti-Spam FireWall by CleanTalk plugin for WordPress is vulnerable to unauthorized Arbitrary Plugin Installation due to an missing empty value check on the ‘api_key’ value in the ‘perform’ function in all versions up to and including 6.44. 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.
