Is this vulnerability remotely exploitable?

Yes. If the WebSocket authentication endpoint is reachable over a network (e.g., the internet, corporate WAN, or operator network), an attacker can remotely send excessive authentication requests.

Does an attacker need valid credentials to exploit this?

No. Exploitation of the denial-of-service aspect requires only the ability to send repeated authentication attempts. Brute-force exploitation requires guessing credentials, but not prior access.

What is the safest general fix pattern?

Introduce robust rate limiting and failure-handling into the authentication flow—such as per-identity throttling, backoff, and temporary lockouts—alongside strong credential requirements and separation of telemetry from authentication traffic.
