Executive Summary

This vulnerability is an Authorization Bypass Through User-Controlled Key issue in the ThimPress LearnPress plugin. It allows attackers to exploit incorrectly configured access control security levels, enabling unauthorized access to data by manipulating IDs in URLs. The flaw is classified as an Insecure Direct Object References (IDOR) vulnerability.

Detection Guidance

Check if your LearnPress plugin version is 4.4.9 or below. Look for unauthorized data exposure or access attempts in server logs. Monitor for unusual URL manipulations involving user IDs or sensitive parameters.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, potentially violating GDPR (data privacy) and HIPAA (health data protection) by allowing access to sensitive user information without proper authorization.

Mitigation Strategies
