- Unprivileged users (if allowed to deploy nodes) can gain admin access to the
Rancher management plane because node driver options intentionally allow
posting certain data to the cloud. The problem is that a user could choose
to post a sensitive file such as /root/.kube/config or
/var/lib/rancher/management-state/cred/kubeconfig-system.yaml.

can be tampered to display arbitrary content, filtering tags but not special
characters or symbols. There's no other limitation of the message.");
