CVE-2025-66404 is a critical command injection vulnerability affecting MCP Server Kubernetes versions prior to 2.9.8. This flaw allows attackers to execute arbitrary commands on the underlying system by injecting shell metacharacters into user-provided input for the 'exec_in_pod' tool, which is passed directly to 'sh -c'. With a CVSS score of 8.8 (HIGH), successful exploitation could lead to complete compromise of confidentiality, integrity, and availability of the Kubernetes cluster. While there is no evidence of active exploitation, public exploit code, or significant community discussion, the high severity warrants immediate patching to version 2.9.8.
