Known exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.

Summary

Open edX Platform, from the Ulmo release until release/ulmo.4 and release/verawood.1, exposes GET /api/support/v1/manage_course_team/ in CourseTeamManageAPIView with only IsAuthenticated, omitting the global support-role check. Any authenticated learner can query arbitrary targets by email, username or user_id and tell active accounts from absent or inactive ones through the 200 and 404 response difference. Callers with a course-level or organization-level instructor role can also read the target's staff or instructor assignments within their own scope.

Mitigation

Fixed in release/ulmo.4 and release/verawood.1.
