Description
The Defender Security – Malware Scanner, Login Security & Firewall plugin for WordPress is vulnerable to Remote Code Execution in all versions up to 6.2.0. This is due to insufficient validation of user supplied input before it is executed. This makes it possible for authenticated attackers, with administrator-level access and above, to execute arbitrary code on the server.
