Advisory Severity Curation

mcp-kubernetes-server has an OS Command Injection vulnerability `feiskyer/mcp-kubernetes-server` through **0.1.11** allows **OS command injection** via the `/mcp/kubectl` endpoint. The handler constructs a shell command with user-supplied arguments and executes it with `subprocess` using `shell=True`, enabling injection through shell metacharacters (e.g., `;`, `&&`, `$()`), even when the server is running in **read-only** mode. A remote, unauthenticated attacker can execute arbitrary OS commands on the host, resulting in full compromise of confidentiality, integrity, and availability. This issue is **distinct from** `mcp-server-kubernetes` and from **CVE-2025-53355**.
