{"cve":"CVE-2026-33060","nvd":{"published":"2026-03-20T08:16:11.923","modified":"2026-06-17T10:36:52.883","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","score":5.7},"cwes":["CWE-918"],"references":["https://github.com/kysely-org/kysely/commit/0a602bff2f442f6c26d5e047ca8f8715179f6d24","https://github.com/ondata/ckan-mcp-server/security/advisories/GHSA-3xm7-qw7j-qc8v"],"products":["ondata:ckan_mcp_server"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33060","score":0.00294,"percentile":0.22041,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-3xm7-qw7j-qc8v","url":"https://osv.dev/vulnerability/GHSA-3xm7-qw7j-qc8v","summary":"SSRF in @aborruso/ckan-mcp-server via base_url allows access to internal networks","modified":"2026-09-23T03:56:42.773817314Z","packages":[{"ecosystem":"npm","name":"@aborruso/ckan-mcp-server","purl":"pkg:npm/%40aborruso/ckan-mcp-server","ranges":["<0.4.85"],"fixed":["0.4.85"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
