Overview
mcp-server-kubernetes is a MCP server for interacting with Kubernetes clusters via kubectl
Affected versions of this package are vulnerable to Arbitrary Argument Injection via the kubectl_generic tool. An attacker can obtain sensitive authentication tokens by injecting malicious flags in an application's log output that redirect API requests to an attacker-controlled server, causing the operator's bearer token to be exfiltrated during command execution. This is only exploitable if an operator with a privileged kubeconfig executes the process and their AI agent or automation follows the injected instructions.
