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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","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,"severity":null}],"references":["https://github.com/Flux159/mcp-server-kubernetes/releases/tag/3.9.0","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/commit/d7890f50a4567bf5d9842541ba6f41e180227f9a","https://www.vulncheck.com/advisories/mcp-server-kubernetes-argument-injection-via-kubectl-structured-tools"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-42987","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Jul 10, 2026, 6:34:27 PM","dateUpdated":"Jul 14, 2026, 10:03:38 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
