- Summary
- mcp-kubernetes-server has an OS Command Injection vulnerability
- Details
-
feiskyer/mcp-kubernetes-serverthrough 0.1.11 allows OS command injection via the/mcp/kubectlendpoint. The handler constructs a shell command with user-supplied arguments and executes it withsubprocessusingshell=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.
