Summary
Long-lived Rancher registration token exposed in plaintext
Details

Rancher issues long-lived registration tokens to authenticate nodes and agents joining a downstream cluster. These tokens were stored and exposed in plaintext with no expiration, so a malicious user could obtain one either through the Rancher API, etcd, stored automation, or direct file access on a node, and could use it at any time to register a rogue node into the cluster.
