Vulnerability Overview

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized course completion in all versions up to, and including, 3.9.2. This is due to missing enrollment verification in the 'mark_course_complete' function. This makes it possible for authenticated attackers, with subscriber level access and above, to mark any course as completed.

Technical Analysis

REMEDIATION: Update to version 3.9.4, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
