## Technical details

The Masteriyo LMS plugin for WordPress is vulnerable to an authentication bypass and broken access control within its REST API. Specifically, the course-progress controller fails to implement proper authorization checks for GET and DELETE requests. An unauthenticated remote attacker can exploit this by sending crafted requests to the `/wp-json/masteriyo/v1/course-progress/items/{id}` endpoint. This allows for the unauthorized disclosure of student activity data (Vector 1) and the permanent deletion of course progress records from the database (Vector 2). The issue is resolved in version 2.2.1, which introduces proper permission checks.

## Affected products
