A CKAN portal client has no legitimate reason to contact cloud metadata or internal network services.\n\n## Severity\n\nAttack complexity is HIGH because exploitation requires prompt injection via malicious content (webpage, document) while the victim's AI assistant has this MCP server connected.\n\n## Proof of Concept\n\nTested inside Docker-in-Docker isolated environment with canary HTTP sidecar.\n\n```json\n{\"tool\": \"ckan_package_search\", \"arguments\": {\"base_url\": \"http://canary:8080/ssrf\", \"query\": \"test\"}}\n```\n**Result**: Canary received **9 HTTP requests**. The high request volume confirms no rate limiting or URL validation.\n\n## Root Cause\n\nNo 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.\n\n## Impact\n\nInternal 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.\n\n## Recommended Fix\n\n1. Validate `base_url` against a configurable allowlist of permitted CKAN portals\n2. Block private IP ranges (RFC 1918, link-local)\n3. Block cloud metadata endpoints (169.254.169.254)\n4. Sanitize SQL input for datastore queries\n5. SPARQL endpoint allowlist\n\n## Credit\n\nDiscovered by [Andrei Boldyrev](https://github.com/abcgco) of Munio Security Research using [munio](https://munio.dev)","state":0,"publishedAt":"2026-03-18T12:59:42+00:00","modifiedAt":"2026-09-23T03:56:42.7738173+00:00","affected":[{"ecosystem":"npm","name":"@aborruso/ckan-mcp-server","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.4.85"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/ondata/ckan-mcp-server/security/advisories/GHSA-3xm7-qw7j-qc8v","https://nvd.nist.gov/vuln/detail/CVE-2026-33060","https://github.com/kysely-org/kysely/commit/0a602bff2f442f6c26d5e047ca8f8715179f6d24","https://github.com/ondata/ckan-mcp-server"],"sourceUrl":"https://github.com/advisories/GHSA-3xm7-qw7j-qc8v","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-3xm7-qw7j-qc8v","identifiers":["GHSA-3xm7-qw7j-qc8v","CVE-2026-33060"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
