mcp-server-kubernetes vulnerabilities

MCP Server Kubernetes before version 3.9.0 contains an argument injection vulnerability in structured tools (kubectl_get, kubectl_describe, kubectl_delete) that allows attackers to bypass the assertNoDangerousFlags security check by supplying resourceType and name parameters with leading dashes. Attackers can inject the --server flag to redirect kubectl commands to an attacker-controlled API server, causing the operator's bearer token to be transmitted externally and enabling full cluster compromise.

mcp-server-kubernetes is a Model Context Protocol server for Kubernetes cluster management. Prior to version 3.7.0, the kubectl_generic tool passes user-supplied flags directly to kubectl without any allowlist, enabling a privilege escalation attack within Kubernetes environments.

mcp-server-kubernetes is a Model Context Protocol server for Kubernetes cluster management. Prior to version 3.6.0, this server exposes three environment variables intended for access control to Kubernetes operations, but these controls were only effective at the tool discovery layer, not at the execution layer.
