Workarounds
CNA: Configure the Feast operator to use a dedicated, minimally-privileged ServiceAccount for the `feast apply` CronJob, ensuring `automountServiceAccountToken: false` is set. Apply a restricted `securityContext` to the CronJob pod and implement network policies to limit egress to only required registry endpoints. Ensure the CronJob ServiceAccount is separate from the feature-server ServiceAccount.
