Is this vulnerability remotely exploitable?

Yes, as described, the administrative HTTP endpoint can be accessed remotely if it is reachable over the network, and missing authentication allows attackers to trigger administrative actions without valid credentials.

Does an attacker need any special privileges or accounts?

No standard user account or privilege is required if the vulnerable endpoint is directly exposed; basic network reachability to the service is typically sufficient.

What is the safest general fix pattern for this issue?

Wrap all administrative and sensitive endpoints with mandatory, consistent authentication and authorization mechanisms, and ensure that admin interfaces are not exposed to untrusted networks by default.
