Summary
Netmaker has Privilege Escalation from Admin to Super-Admin via User Update
Details

The user update handler (PUT /api/users/{username}) lacks validation to prevent an admin-role user from assigning the super-admin role during account updates. While the code correctly blocks an admin from assigning the admin role to another user, it does not include an equivalent check for the super-admin role.
