CVE-2026-19516: CWE-918 in Grafana Grafana MCP Server

VulnerabilityCVE-2026-19516cvecve-2026-19516cwe-918
Published: 08/11/2026 (08/11/2026, 05:28:30 UTC)
Source: CVE Database V5
Vendor/Project: Grafana
Product: Grafana MCP Server

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.
