Prior to 0.4.112, error paths reflect raw upstream response bodies and internal exception messages back to the caller instead of a sanitized, generic message. When the server is pointed at (or redirected/SSRF'd to) a host that returns a non-CKAN response, or when an internal exception occurs, the caller receives verbatim upstream content and internal detail (hostnames, internal IPs, DB errors, stack fragments). This vulnerability is fixed in 0.4.112.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7},"cwes":["CWE-209","CWE-210"],"references":["https://github.com/ondata/ckan-mcp-server/commit/3b827af72b228d42aa7b0d7dac5347d16af3f4e5","https://github.com/ondata/ckan-mcp-server/releases/tag/v0.4.112","https://github.com/ondata/ckan-mcp-server/security/advisories/GHSA-6f9w-9hf2-5rg3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-73844","score":0.00355,"percentile":0.292,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-6f9w-9hf2-5rg3","url":"https://osv.dev/vulnerability/GHSA-6f9w-9hf2-5rg3","summary":"CKAN MCP Server: Information disclosure via verbose error reflection","modified":"2026-09-03T15:00:09.614213883Z","packages":[{"ecosystem":"npm","name":"@aborruso/ckan-mcp-server","purl":"pkg:npm/%40aborruso/ckan-mcp-server","ranges":["<0.4.112"],"fixed":["0.4.112"]}]}],"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).
