{"id":"GHSA-hjm5-xgj8-vwj6","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 \u003cname\u003e`). 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.","aliases":["CVE-2025-59376","PYSEC-2026-1619"],"modified":"2026-07-07T17:57:11.934816555Z","published":"2025-09-15T15:31:24Z","database_specific":{"cwe_ids":["CWE-77"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2025-09-15T21:37:47Z","nvd_published_at":"2025-09-15T14:15:44Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59376"},{"type":"PACKAGE","url":"https://github.com/feiskyer/mcp-kubernetes-server"},{"type":"WEB","url":"https://github.com/feiskyer/mcp-kubernetes-server/blob/78957b6c1a3982080cf6fcaac6f6e9014116a71c/src/mcp_kubernetes_server/main.py#L106-L137"},{"type":"WEB","url":"https://github.com/william31212/CVE-Requests-1896609"}],"affected":[{"package":{"name":"mcp-kubernetes-server","ecosystem":"PyPI","purl":"pkg:pypi/mcp-kubernetes-server"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"0.1.11"}]}],"versions":["0.1.0","0.1.1","0.1.10","0.1.11","0.1.2","0.1.3","0.1.4","0.1.5","0.1.6","0.1.7","0.1.8","0.1.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/09/GHSA-hjm5-xgj8-vwj6/GHSA-hjm5-xgj8-vwj6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
