npm/@aborruso/ckan-mcp-server@aborruso/ckan-mcp-server has SSRF via DNS-name → internal IP — incomplete fix of CVE-2026-53509

Risk 33
Severity
5.7
SSRF
AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N

CKAN MCP Server is a tool for querying CKAN open data portals. 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. Any caller-supplied serverurl whose hostname resolves to an internal address passes the guard, so the server issues requests to loopback and cloud metadata (169.254.169.254). This is a third bypass of the same guard, and it reaches IMDS — strictly more than CVE-2026-53509, which only reached loopback. Version 0.4.108 contains an updated fix.
