Hunt for node-level Kubernetes endpoints that are reachable and under-authenticated: a kubelet API that allows anonymous or unauthenticated requests to list pods, read logs, or exec into containers, a read-only kubelet port exposing pod and node data, a node-local metadata or debug endpoint reachable from a pod, and a kubelet authorization mode that authenticates but does not restrict what a caller can do. Covers Kubernetes nodes where the kubelet and other node-local services expose control…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hunting kubelet and node API exposure: the control plane on every node Every Kubernetes node runs a kubelet, and the kubelet is a powerful local API: it can list the pods on the node, stream their logs, and exec into their containers. That makes each node a small control plane, and the kubelet's authentication and authorization are the only thing between a caller who can reach it and node-level control over every pod scheduled there. The exposures are concrete: a kubelet configured to allow anonymous requests, a read-only port that serves pod and node data without auth, an authorization mode that authenticates the caller but then allows the action anyway, and reachability from a pod or the network that should never have existed. A caller who reaches an under-authenticated kubelet can read secrets from other pods' environments, exec into neighbors, and pivot. You hunt this by finding node endpoints that are reachable and testing whether their authentication actually refuses an unauthorized caller. ## When to use - Kubelet or other node-local endpoints may be reachable from pods or the surrounding network. …

How to install
mdr add unboundcompute/security-agent-skills/hunting-kubelet-and-node-api-exposure@sha256:62c1126522e198d5The line at the top of this page pins the label git:20260828.ce55026, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
