Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The mcp-kubernetes-server package, versions through 0.1.11, is vulnerable to OS command injection via its /mcp/kubectl endpoint. The handler builds a shell command from user-supplied arguments and runs it with shell=True, so a remote, unauthenticated attacker can execute arbitrary OS commands on the host, even when the server is in read-only mode. No fixed version is listed.
