The charging station websocket endpoint accepts connections without proper authentication, which could lead to privilege escalation.

Multiple connections to the backend using the same charging station ID are allowed, which could allow an attacker to deploy multiple instances of malicious OCPP clients to overwhelm the backend.

Previously, there was no throttling on repeated authentication attempts to the charging station backend, which could allow an attacker to execute a denial-of-service attack.
