What is CVE-2026-4484?

The Masteriyo LMS plugin for WordPress is susceptible to privilege escalation vulnerabilities that allow authenticated users, with Student-level access or higher, to modify their user role. This exploit arises from the 'InstructorsController::prepare_object_for_database' function, which inadequately verifies user permissions, enabling attackers to escalate their privileges to that of an administrator. This situation poses significant security risks to WordPress sites using the affected plugin versions.

Affected Version(s)

Masteriyo LMS – Online Course Builder for eLearning, LMS & Education 0 <= 2.1.6
