CyberRota Analysis
AI-GeneratedThe vulnerability allows an attacker to manipulate the X-Grafana-URL request header in mcp-grafana, enabling them to perform server-side request forgery (SSRF) by directing requests to internal network services, including sensitive metadata endpoints. This can lead to unauthorized access to internal resources and potential data exposure. Organizations using mcp-grafana should prioritize addressing this critical vulnerability to mitigate risks associated with SSRF attacks.
Original NVD Description
A caller-supplied X-Grafana-URL request header controls the destination of mcp-grafana's outbound requests, and the grafana_api_request tool lets the caller also choose the HTTP method, path, and body. Because the destination is not restricted to the configured Grafana instance, a caller can direct requests at internal, loopback, and link-local network services (including metadata endpoints) and read the responses, resulting in server-side request forgery. The fix for CVE-2026-15583 prevented the configured service-account token from being sent to unintended destinations but did not restrict the destinations themselves.
