Executive Summary

This vulnerability affects the MasterStudy LMS WordPress plugin versions before 3.7.50. It allows any authenticated user, including low-privilege users like subscribers, to perform administrative maintenance actions without proper checks. This lets them create published courses or lessons on the site, with the content attributed to their own account.

Detection Guidance

Check the installed version of the MasterStudy LMS plugin. If it is between 2.3.0 and 3.7.49, the system is vulnerable. Log in as a subscriber and attempt to access administrative maintenance actions to see if unauthorized content creation is possible.

Impact Analysis

An attacker could exploit this to create unauthorized content on your WordPress site, potentially spreading misinformation, malicious links, or inappropriate material. Since the content appears under the attacker's account, it may go unnoticed until significant damage is done.

Compliance Impact

This vulnerability allows unauthorized users to create published content on the site, which could lead to data integrity issues or unauthorized data exposure. For GDPR, this may violate principles of data protection and user consent. For HIPAA, it could compromise protected health information integrity if course content involves such data.

Mitigation Strategies

Update the MasterStudy LMS plugin to version 3.7.50 or later immediately. If updating is not possible, consider temporarily disabling the plugin until the update can be applied.
