Is this vulnerability remotely exploitable?

Yes. Any attacker who can reach the host and port where the WhatsApp bridge's WebSocket server listens (typically 0.0.0.0:3001) can attempt to hijack the session without authentication.

What level of access does an attacker need?

The attacker only needs network access to the exposed port. No valid user credentials, tokens, or prior foothold on the host are required if the bridge is reachable over the network.

What is the safest general fix pattern?

Restrict the WebSocket server's exposure and require strong authentication and authorization for all operations. This typically includes binding the server to a non-public interface or localhost, enforcing authenticated sessions, and validating that each action is authorized for the caller.
