Vulnerability Title
Netmaker: Privilege Escalation from Admin to Super-Admin via User Update
Source: CVE Program / CVE List V5
Vulnerability Description
Netmaker makes networks with WireGuard. Prior to version 1.5.0, 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. This issue has been patched in version 1.5.0.
