Attackers can inject the --server flag to redirect kubectl commands to an attacker-controlled API server, causing the operator's bearer token to be transmitted externally and enabling full cluster compromise.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-88"],"references":["https://github.com/Flux159/mcp-server-kubernetes/commit/d7890f50a4567bf5d9842541ba6f41e180227f9a","https://github.com/Flux159/mcp-server-kubernetes/issues/328","https://github.com/Flux159/mcp-server-kubernetes/pull/329","https://github.com/Flux159/mcp-server-kubernetes/releases/tag/3.9.0","https://www.vulncheck.com/advisories/mcp-server-kubernetes-argument-injection-via-kubectl-structured-tools"],"products":["suyogs:mcp-server-kubernetes"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-61459","score":0.02362,"percentile":0.83661,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-wmg3-h8mf-wgvr","url":"https://osv.dev/vulnerability/GHSA-wmg3-h8mf-wgvr","summary":"mcp-server-kubernetes argument injection can expose Kubernetes cluster credentials","modified":"2026-08-19T12:55:51.779516464Z","packages":[{"ecosystem":"PyPI","name":"mcp-server-kubernetes","purl":"pkg:pypi/mcp-server-kubernetes","ranges":["<3.9.0"],"fixed":["3.9.0"]}]},{"id":"PYSEC-2026-3685","url":"https://osv.dev/vulnerability/PYSEC-2026-3685","summary":"mcp-server-kubernetes argument injection can expose Kubernetes cluster credentials","modified":"2026-08-19T12:45:06.485001885Z","packages":[{"ecosystem":"PyPI","name":"mcp-server-kubernetes","purl":"pkg:pypi/mcp-server-kubernetes","ranges":["<3.9.0"],"fixed":["3.9.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
