From: Soumya Sambu <[email protected]> Users may be able to launch containers using images that are restricted by ImagePolicyWebhook when using ephemeral containers, Kubernetes clusters are only affected if the ImagePolicyWebhook admission plugin is used together with ephemeral containers.
Users may be able to launch containers that bypass the mountable secrets policy enforced by the ServiceAccount admission plugin when using ephemeral containers. The policy ensures pods running with a service account may only reference secrets specified in the service account's secrets field. Kuberenetes clusters are only affected if the ServiceAccount admission plugin and the `kubernetes.io/enforce-mountab'le-secrets` annotation are used teogether with ephemeralcontainers.
