Is this vulnerability remotely exploitable?

Yes. If the WebSocket API is reachable over a network (such as the public internet or a corporate WAN), an attacker can exploit the missing rate limiting remotely by sending large numbers of authentication requests.

What level of access does an attacker need?

The attacker only needs the ability to establish WebSocket connections to the affected API endpoint. No prior authentication is required to exploit the absence of rate limiting on authentication attempts.

What is the safest general fix pattern?

The most robust fix is to add layered rate limiting and abuse protections around authentication: enforce per-identity and per-source limits, implement backoff and temporary lockouts after repeated failures, and ensure authentication handling is isolated from core telemetry or control processing.
