Technical details

The vulnerability is a missing authorization check (CWE-862) in the backend import endpoints for tests and questions. Low-privileged authenticated users (e.g., students) can bypass authorization controls by sending direct requests to these endpoints, allowing unauthorized import operations within a course. The attack requires an authenticated account and course enrollment but does not require instructor/administrator privileges. ATutor 2.2.4 is confirmed vulnerable; other versions are unknown. The product is no longer actively maintained and no patch is available.
