What the vulnerability does

01Description

The WPCasa plugin for WordPress is vulnerable to Code Injection in all versions up to, and including, 1.4.1. This is due to insufficient input validation and restriction on the 'api_requests' function. This makes it possible for unauthenticated attackers to call arbitrary functions and execute code.
