Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

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 <name>). 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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mcp-kubernetes-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of mcp-kubernetes-server for CVE-2025-59376. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
