Is this vulnerability remotely exploitable over the network?

Not in a direct, unauthenticated network sense. Exploitation typically requires an attacker to gain a path to modify the YAML configuration files used by the Kubernetes materializer job, which may occur through compromised CI/CD systems, misconfigured volumes, or other indirect supply-chain and infrastructure weaknesses.

What level of access does an attacker need to exploit this issue?

The attacker needs the ability to influence or overwrite `/var/feast/feature_store.yaml` or `/var/feast/materialization_config.yaml`. This might be via local file-system access in the container or node, write access to a mounted config source, or control over the process that generates or distributes these configuration files.

What is the safest general fix pattern, independent of version updates?

The safest pattern is to switch from generic, object-capable deserialization to strictly data-oriented parsing. Concretely, use safe YAML loaders or equivalent APIs that do not allow arbitrary object construction, and enforce a clear schema for configuration files so that unexpected structures or tags are rejected rather than interpreted.
