CVE-2026-61612

NVD: CKAN MCP Server is a tool for querying CKAN open data portals. NVD: Prior to version 0.4.108, the SSRF guard validateServerUrl (added for CVE-2026-33060, extended for CVE-2026-53509) validates only the hostname string and never resolves DNS. NVD: Any caller-supplied server_url whose hostname *resolves* to an internal address passes the guard, so the server issues requests to loopback and cloud metadata (169.254.169.254).
