Is this vulnerability remotely exploitable?

Yes. If the WebSocket authentication endpoint is reachable over a network (e.g., the internet or a wide-area operational network), an attacker can exploit the missing rate limits remotely by sending high-frequency or high-volume authentication messages.

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

The attacker primarily needs network access to the WebSocket API. No prior authentication is required to initiate excessive authentication attempts, though insider or adjacent network access can also be sufficient if the service is not publicly exposed.

What is the safest general fix pattern?

Apply robust, server-side rate limiting and abuse controls to the authentication flow: cap the number of attempts per identity and per source, introduce incremental delays or lockouts after repeated failures, and ensure that abusive connections can be throttled or terminated without affecting legitimate traffic.
