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.

Notes

Author Note
leosilva kubernates is in fact a kubernetes installer that calls snap, not the package it self.
