Is this vulnerability remotely exploitable?

Yes. Any attacker who can position themselves on the network path between Ayms node-To master and its TLS peer can remotely exploit the issue to intercept or alter traffic.

Does this vulnerability require authentication or local access?

It does not require local access to the host. The attacker only needs network-level access to observe and manipulate traffic; no authentication to the application itself is required to perform a man-in-the-middle attack.

What is the safest general fix pattern for this issue?

Re-enable proper TLS certificate validation by removing `rejectUnauthorized: false` and relying on the default validation logic, ensuring the correct trust store is used, and enabling hostname verification. Any temporary debugging or "trust-all" settings should be removed from production paths.
