Summary
MCP Server Kubernetes < 3.9.0 Argument Injection via kubectl Structured Tools
Details

MCP Server Kubernetes before 3.9.0 contains an argument injection vulnerability in structured tools (kubectlget, kubectldescribe, 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.
