Title
SSRF (confused deputy) in Grafana MCP Server via X-Grafana-URL header
Summary
A confused-deputy flaw in Grafana MCP Server allows an unauthenticated remote attacker to exfiltrate the server's environment-configured Grafana service-account token by supplying a crafted X-Grafana-URL request header. This also enables SSRF against arbitrary internal services, including cloud metadata endpoints.
