Technical details
The getGroupUserList API handler in group_user_api.py lacks authorization checks: it verifies authentication but does not validate that the requesting user belongs to the queried group before returning member details. An authenticated attacker can enumerate group_id values to retrieve group membership, leader flags, edit permissions, and owner usernames from any group in the system.
