Technical details
The vulnerability is an insecure direct object reference (IDOR) in the course enrollment data endpoint. The plugin fails to verify that the requesting instructor owns a course before returning enrolled-student information, allowing an authenticated instructor to enumerate and retrieve student PII from courses they do not manage. The attack requires an active instructor account but no additional user interaction; the attacker can directly request student data for any course ID. The vulnerability is fixed in version 3.7.50 and later.
