{"id":"CVE-2026-33060","summary":"CKAN MCP Server: SSRF via base_url allows access to internal networks","details":"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.","aliases":["GHSA-3xm7-qw7j-qc8v"],"modified":"2026-08-12T03:51:48.444039214Z","published":"2026-03-20T07:21:30.897Z","database_specific":{"cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33060.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33060.json"},{"type":"ADVISORY","url":"https://github.com/ondata/ckan-mcp-server/security/advisories/GHSA-3xm7-qw7j-qc8v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33060"},{"type":"FIX","url":"https://github.com/kysely-org/kysely/commit/0a602bff2f442f6c26d5e047ca8f8715179f6d24"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kysely-org/kysely","events":[{"introduced":"0"},{"fixed":"0a602bff2f442f6c26d5e047ca8f8715179f6d24"}],"database_specific":{"source":"REFERENCES"}},{"type":"GIT","repo":"https://github.com/ondata/ckan-mcp-server","events":[{"introduced":"0"},{"fixed":"a784036e377a17ecf8d05bc1c142be98a6d43af4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.4.85"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:ondata:ckan_mcp_server:*:*:*:*:*:node.js:*:*"}}],"versions":["v0.28.11","v0.28.10","v0.28.9","v0.28.8","v0.28.7","v0.28.6","v0.28.5","v0.28.4","v0.28.3","0.28.2","0.28.1","0.28.0","0.27.6","0.27.5","0.27.4","0.27.3","0.27.2","0.27.1","0.27.0","0.26.3","0.26.2","0.26.1","0.26.0","0.25.0","0.24.2","0.24.0","0.23.5","0.23.4","0.23.3","0.23.2","0.23.1","0.23.0","0.22.0","0.21.6","0.21.5","0.21.4","0.21.3","0.21.2","0.21.1","0.21.0","0.20.1","0.20.0","0.19.12","0.19.11","0.19.10","0.19.9","0.19.8","0.19.7","0.19.6","0.19.5","0.19.4","0.19.3","0.19.2","0.19.1","0.19.0","0.18.1","0.18.0","0.17.3","0.17.2","0.17.0","0.16.11","0.16.10","0.16.9","0.16.8","0.16.7","0.16.6","0.16.5","0.16.4","0.16.3","0.16.2","0.16.1","0.16.0","0.15.3","0.15.2","0.15.1","0.15.0","0.14.1","0.14.0","0.13.0","0.12.2","0.12.1","0.12.0","0.11.4","0.11.3","0.11.2","0.11.1","0.11.0","0.10.1","0.10.0","0.9.9","0.9.8","0.9.7","0.9.6","0.9.5","0.9.4","0.9.3","0.9.2","0.9.1","0.9.0","0.7.9","0.7.8","v0.4.84","v0.4.83","v0.4.82","v0.4.81","v0.4.80","v0.4.79","v0.4.78","v0.4.77","v0.4.76","v0.4.75","v0.4.74","v0.4.73","v0.4.72","v0.4.71","v0.4.69","v0.4.68","v0.4.67","v0.4.66","v0.4.65","v0.4.64","v0.4.63","v0.4.62","v0.4.61","v0.4.60","v0.4.59","v0.4.58","v0.4.57","v0.4.56","v0.4.55","v0.4.54","v0.4.53","v0.4.52","v0.4.51","v0.4.50","v0.4.49","v0.4.48","v0.4.47","v0.4.46","v0.4.45","v0.4.44","v0.4.43","v0.4.42","v0.4.41","v0.4.40","v0.4.39","v0.4.38","v0.4.37","v0.4.36","v0.4.35","v0.4.34","v0.4.33","v0.4.32","v0.4.31","v0.4.30","v0.4.29","v0.4.28","v0.4.27","v0.4.26","v0.4.25","v0.4.24","v0.4.23","v0.4.22","v0.4.21","v0.4.20","v0.4.19","v0.4.18","v0.4.17","v0.4.16","v0.4.15","v0.4.14","v0.4.13","v0.4.12","v0.4.11","v0.4.10","v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.2","v0.3.1","v0.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33060.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
