{"id":"CVE-2026-33060","state":"PUBLISHED","title":"CKAN MCP Server: SSRF via base_url allows access to internal networks","description":"CKAN MCP Server is a tool for querying CKAN open data portals. Versions prior to 0.4.85 provide tools including ckan_package_search and sparql_query that accept a base_url parameter, making HTTP requests to arbitrary endpoints without restriction. A CKAN portal client has no legitimate reason to contact cloud metadata or internal network services. There is no URL validation on base_url parameter. No private IP blocking (RFC 1918, link-local 169.254.x.x), no cloud metadata blocking. The sparql_query and ckan_datastore_search_sql tools also accept arbitrary base URLs and expose injection surfaces. An attack can lead to internal network scanning, cloud metadata theft (IAM credentials via IMDS at 169.254.169.254), potential SQL/SPARQL injection via unsanitized query parameters. Attack requires prompt injection to control the base_url parameter. This issue has been fixed in version 0.4.85.","publishedAt":"2026-03-20T07:21:30.897Z","updatedAt":"2026-03-24T01:56:33.169Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["ondata ckan-mcp-server"],"affected":[{"vendor":"ondata","product":"ckan-mcp-server","versions":[{"version":"< 0.4.85","status":"affected"}]}],"references":["https://github.com/ondata/ckan-mcp-server/security/advisories/GHSA-3xm7-qw7j-qc8v","https://github.com/kysely-org/kysely/commit/0a602bff2f442f6c26d5e047ca8f8715179f6d24"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33060.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33060","state":"PUBLISHED","datePublished":"2026-03-20T07:21:30.897Z","dateUpdated":"2026-03-24T01:56:33.169Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-17T19:27:06.342Z"},"containers":{"cna":{"title":"CKAN MCP Server: SSRF via base_url allows access to internal networks","descriptions":[{"lang":"en","value":"CKAN MCP Server is a tool for querying CKAN open data portals.
