WordPress Member Hero plugin through 1.0.9 is susceptible to remote code execution. The plugin lacks authorization checks and does not validate the a request parameter in an AJAX action, allowing an attacker to call arbitrary PHP functions with no arguments. An attacker can thus execute malware, obtain sensitive information, modify data, and/or gain full control over a compromised system without entering necessary credentials.
