Vulnerability Title
CVE-2026-19516 CVE Record
Source: CVE Program / CVE List V5
Vulnerability 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.

Vulnerability Title
Grafana MCP Server 服务端请求伪造漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Grafana MCP Server是Grafana公司的一款数据可视化与监控服务器软件。 Grafana MCP Server和mcp-grafana 1.0.0及之前版本存在服务端请求伪造漏洞，该漏洞源于未对X-Grafana-URL请求头控制的目标进行限制，且grafana_api_request工具允许调用者选择HTTP方法、路径和主体，可能导致攻击者将请求定向到内部、回环和链路本地网络服务并读取响应，造成服务端请求伪造。
