Descriptions

The MasterStudy LMS WordPress Plugin WordPress plugin before 3.3.24 does not prevent students from creating instructor accounts, which could be used to get access to functionalities they shouldn't have.

El complemento de WordPress MasterStudy LMS WordPress Plugin anterior a 3.3.24 no impide que los estudiantes creen cuentas de instructor, que podrían usarse para obtener acceso a funcionalidades que no deberían tener.

The MasterStudy LMS WordPress Plugin – for Online Courses and Education plugin for WordPress is vulnerable to limited privilege escalation in all versions up to, and including, 3.3.23. This is due to insufficient role restrictions when registering through the stm_lms_register AJAX endpoint. This makes it possible for unauthenticated attackers to register on sites with Instructor level access.
