Description
The Tutor LMS Pro – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.8.3 due to missing validation on a user controlled key when viewing and editing assignments through the tutor_assignment_submit() function.
