Is this vulnerability remotely exploitable?

Yes, as long as an attacker can reach the WireGuard Portal over the network and obtain any valid non-admin account, they can exploit this issue by sending a crafted HTTP request.

Does an attacker need administrative access to exploit this?

No. Exploitation only requires an authenticated non-admin user. Once logged in, the attacker can modify their own profile payload to set `"IsAdmin": true` and gain admin privileges after re-authentication.

What is the safest general fix pattern for this class of bug?

Treat privilege and role fields as strictly server-controlled. Use explicit allow-lists for which fields can be updated from user input, and isolate role/privilege changes into dedicated, admin-only endpoints with clear authorization checks and auditing.
