Affected packages
• PyPI mcp-kubernetes-server: <= 0.1.11 (no fix yet)
Description
`mcp-kubernetes-server` does not correctly enforce the `--disable-write` / `--disable-delete` protections when commands are chained. The server only inspects the first token to decide whether an operation is write/delete, which allows a read-like command to be followed by a write action using shell metacharacters (e.g., `kubectl version; kubectl delete pod `). A remote attacker who can invoke the server may therefore bypass the intended write/delete restrictions and perform state-changing operations against the Kubernetes cluster.
Affected versions: through `0.1.11` (no patched release available as of now).
Mitigations:
• Run with `--disable-kubectl` and/or `--disable-helm` to fully block those execution paths.
• Put the server behind an allow-list proxy restricting allowed subcommands.
