{"id":"CVE-2026-33060","aliases":["GHSA-3xm7-qw7j-qc8v"],"url":"https://o3.security/vulnerability/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.","published":"2026-03-20T07:21:30.897Z","modified":"2026-07-15T01:49:06.029413846Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@aborruso/ckan-mcp-server","fixedVersion":"0.4.85"}],"fix":{"url":"https://github.com/kysely-org/kysely/commit/0a602bff2f442f6c26d5e047ca8f8715179f6d24","label":"kysely-org/kysely@0a602bf"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:06.029413846Z"}}
