Mitigation checklist

Recommended fix / mitigation

Restrict the insights-client ClusterRole to the minimum required permissions. Replace the cluster-wide secrets get/list/watch with a namespaced Role granting get access only to the specific Secret openshift-config/pull-secret in the openshift-config namespace.
