Summary
The Academy LMS WordPress plugin before 4.0.0 does not verify course enrollment or object ownership when returning a lesson's content through one of its REST API routes. This allows users with a self-registerable student account to read the full content of arbitrary lessons, including lessons of paid or private courses they are not enrolled in.
Risk Assessment
An attacker can access paid or private course content without authorization, leading to revenue loss and breach of material confidentiality. This undermines the educational platform's business model.
Recommendation
Update the Academy LMS plugin to version 4.0.0 or later. Check whether any unauthorized access to lesson content has occurred.
