Is this vulnerability remotely exploitable?

Yes. If the Agent Mode Service is network-exposed without additional protections (such as reverse proxies enforcing auth), a remote attacker who can reach the service can attempt to exploit the missing authentication.

Does an attacker need a valid account or credentials?

Not necessarily. The described weakness is that certain Agent Mode Service operations either do not enforce authentication or do so incorrectly, allowing unauthenticated access when the interface is reachable.

What is the safest general fix pattern?

Enforce strict authentication and authorization on every Agent Mode Service endpoint, ideally via centralized middleware or an API gateway, and ensure that only authenticated, authorized identities can trigger sensitive agent actions.
