{"id":"CVE-2025-59376","aliases":["GHSA-hjm5-xgj8-vwj6","PYSEC-2026-1619"],"url":"https://o3.security/vulnerability/CVE-2025-59376","summary":"mcp-kubernetes-server has a Command Injection vulnerability","details":"`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.\n\n**Affected versions:** through `0.1.11` (no patched release available as of now).\n\n**Mitigations:**\n- Run with `--disable-kubectl` and/or `--disable-helm` to fully block those execution paths.\n- Put the server behind an allow-list proxy restricting allowed subcommands.","published":"2025-09-15T00:00:00Z","modified":"2026-08-12T03:51:11.250352246Z","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":null,"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/main.py#L106-L137"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59376.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59376"},{"type":"PACKAGE","url":"https://github.com/william31212/CVE-Requests-1896609"},{"type":"PACKAGE","url":"https://github.com/feiskyer/mcp-kubernetes-server"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.250352246Z"}}
