Is this vulnerability remotely exploitable?

Yes. If the OCPP WebSocket endpoint is reachable from the internet or other untrusted networks, an attacker can remotely connect and impersonate charging stations without prior access.

What level of access does an attacker need to exploit this?

The attacker only needs network access to the WebSocket endpoint. No valid credentials are required; knowing or guessing a station identifier is typically sufficient.

What is the safest general fix pattern?

Introduce robust device authentication for all OCPP WebSocket connections, ensuring that every station presents a cryptographically verifiable identity bound to its station ID, and enforce authorization checks before accepting or processing commands.
