Executive Summary

This vulnerability is an Insecure Direct Object Reference (IDOR) in the Tutor LMS Pro WordPress plugin up to version 3.8.3. It occurs because the plugin does not properly validate a user-controlled key when users view and edit assignments via the tutor_assignment_submit() function. As a result, authenticated users with Subscriber-level access or higher can view and modify assignment submissions belonging to other students.

Impact Analysis

The vulnerability allows attackers with at least Subscriber-level access to view and edit other students' assignment submissions. This can lead to unauthorized disclosure of sensitive information and unauthorized modification of academic records, potentially undermining the integrity of the eLearning platform and causing trust issues among users.
