Is this vulnerability remotely exploitable?

Yes. As long as the registration endpoint is network-accessible, a remote attacker can exploit it by sending a crafted registration request with an elevated `role` value.

Does an attacker need an existing account or authentication to exploit this issue?

No. Exploitation occurs during the registration process itself, so no prior account or authentication is required.

What is the safest general fix pattern for this vulnerability?

Move all role assignment logic to the server side, enforce a default low-privilege role for self-registrations, and reject or ignore any client-supplied role or privilege fields in registration requests.
