Technical details

The set_default_certificate endpoint in GradebookController lacks authentication and authorization checks, allowing unauthenticated users to set default certificates for any course by specifying arbitrary course and document IDs. An attacker can directly invoke the endpoint to associate malicious or undeserved certificates with courses. The vulnerability was fixed by adding role-based access controls requiring platform admin, session admin, or teacher privileges.
