Is this vulnerability remotely exploitable?

It can be, depending on how challenges and instances are exposed. If an external attacker can obtain code execution inside an instance Pod (for example, through a challenge or another application flaw), they can then use this vulnerability to move laterally to other Pods in the cluster.

What level of access is required to exploit this issue?

The attacker needs the ability to run code or commands inside an instance Pod managed by Chall-Manager. No direct access to the Kubernetes API is required; the misconfigured NetworkPolicy exposes the network path automatically once the Pod is compromised.

What is the safest general fix pattern?

Implement strict, deny-by-default NetworkPolicies around instance Pods, ensuring they can only communicate with explicitly defined, necessary services and are blocked from reaching Pods in other namespaces or trust zones.
