Advisory

Source description from Wordfence Intelligence, credited to Steven Julian.

The Masteriyo LMS – eLearning and Online Course Builder for WordPress plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the update_logged_in_user() function in all versions up to, and including, 1.7.2. This makes it possible for unauthenticated attackers to elevate their privileges to that of an administrator.
