Preliminary research

Kubernetes Remote Code Execution Via Nodes/Proxy GET Permission

Graham Helton · Graham Helton

AI-collected research leads through 2 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.

Shows that Kubernetes `nodes/proxy` GET permission can authorize a WebSocket upgrade to the kubelet `/exec` endpoint without a corresponding create check. The study demonstrates commands in reachable pods, missing API audit visibility and 69 affected Helm charts.
