Vulnerability details

feiskyer mcp-kubernetes-server through 0.1.11 allows OS command injection, even in read-only mode, via /mcp/kubectl because shell=True is used. NOTE: this is unrelated to mcp-server-kubernetes and CVE-2025-53355.

Why these techniques?

CVE-2025-59377 enables OS command injection via shell=True in the network-exposed mcp-kubernetes-server's /mcp/kubectl endpoint, facilitating Unix Shell execution (T1059.004), exploitation of a public-facing application (T1190), exploitation of remote services (T1210), and defense evasion by bypassing read-only/write-delete restrictions (T1211).

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
