Is this vulnerability remotely exploitable?

Yes. If the OCPP WebSocket endpoint is reachable over the internet or an untrusted network and does not enforce strong authentication, an attacker can exploit it remotely by connecting as a fake charging station.

Does an attacker need prior access or valid credentials?

No traditional user credentials are required. The attacker generally only needs network access and knowledge or a guess of a valid station identifier, which may be predictable, leaked, or observable.

What is the safest general fix pattern?

Introduce mandatory, robust authentication for every WebSocket connection, such as mutual TLS with per-device certificates or cryptographically strong tokens, and bind the logical station ID to these credentials rather than trusting the ID alone.
