The handler constructs a shell command with user-supplied arguments and executes it with `subprocess` using `shell=True`, enabling injection through shell metacharacters (e.g., `;`, `&&`, `$()`), even when the server is running in **read-only** mode.\n\nA remote, unauthenticated attacker can execute arbitrary OS commands on the host, resulting in full compromise of confidentiality, integrity, and availability.\n\nThis issue is **distinct from** `mcp-server-kubernetes` and from **CVE-2025-53355**.","published":"2025-09-15T00:00:00Z","modified":"2026-08-12T03:51:24.933734587Z","cvss":{"score":3.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":{"score":0.01203,"percentile":0.6615,"asOf":"2026-09-03"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"mcp-kubernetes-server","fixedVersion":null}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/feiskyer/mcp-kubernetes-server/blob/78957b6c1a3982080cf6fcaac6f6e9014116a71c/src/mcp_kubernetes_server/command.py#L38"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59377.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59377"},{"type":"PACKAGE","url":"https://github.com/william31212/CVE-Requests-1896609"},{"type":"PACKAGE","url":"https://github.com/feiskyer/mcp-kubernetes-server"},{"type":"WEB","url":"https://www.tenable.com/cve/CVE-2025-59377"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:24.933734587Z"}}
