CVE-2026-4484
CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
The Masteriyo LMS plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.1.6. This is due to the plugin allowing a user to update the user role through the InstructorsController::prepare_object_for_database function. This makes it possible for authenticated attackers, with Student-level access and above, to elevate their privileges to that of an administrator.
