Name of the Vulnerable Software and Affected Versions Grafana MCP Server (affected versions not specified)

Description A confused-deputy flaw allows an unauthenticated remote attacker to exfiltrate the environment-configured Grafana service-account token. This is achieved by providing a crafted X-Grafana-URL request header. Additionally, this issue enables Server-Side Request Forgery (SSRF), which allows the attacker to make requests to arbitrary internal services, including cloud metadata endpoints. SSRF is a technique where an attacker induces a server-side application to make requests to an unintended location.
