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.","state":0,"publishedAt":"2026-07-10T19:17:27.45+00:00","modifiedAt":"2026-10-25T15:10:00.147+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1 · disclosure@vulncheck.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"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"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-61459","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-88"],"productCriteria":["cpe:2.3:a:suyogs:mcp-server-kubernetes:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-07-10T19:17:27.450","lastModified":"2026-10-25T15:10:00.147"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
