Is this vulnerability remotely exploitable?

Yes. As long as the OpenAPI endpoints are reachable over the network, an attacker can exploit the missing authentication remotely without prior access.

Does an attacker need valid credentials to exploit this?

No. The core issue is that certain endpoints fail to enforce authentication at all, so attackers only need network connectivity to the affected OpenAPI interface.

What is the safest general fix pattern?

Apply a centralized, default-deny authentication policy to all API routes and verify that the OpenAPI endpoints are covered by standard security configuration rather than relying solely on custom interceptor exclusions.
