Grafana MCP Server: server-side request forgery
High8.6CVE-2026-15583 · Published Jul 15, 2026
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.
