CVE-2024-2409: masterstudy lms — Fix

Description

The MasterStudy LMS plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.3.1. This is due to insufficient validation checks within the _register_user() function called by the 'wp_ajax_nopriv_stm_lms_register' AJAX action. This makes it possible for unauthenticated attackers to register a user with administrator-level privileges when MasterStudy LMS Pro is installed and the LMS Forms Editor add-on is enabled.
