{"id":"CVE-2026-73844","summary":"CKAN MCP Server: Information disclosure via verbose error reflection","details":"CKAN MCP Server is a tool for querying CKAN open data portals. 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.","aliases":["GHSA-6f9w-9hf2-5rg3"],"modified":"2026-08-19T03:31:15.965912210Z","published":"2026-08-14T16:41:42.975Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-209","CWE-210"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73844.json"},"references":[{"type":"WEB","url":"https://github.com/ondata/ckan-mcp-server/releases/tag/v0.4.112"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73844.json"},{"type":"ADVISORY","url":"https://github.com/ondata/ckan-mcp-server/security/advisories/GHSA-6f9w-9hf2-5rg3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73844"},{"type":"FIX","url":"https://github.com/ondata/ckan-mcp-server/commit/3b827af72b228d42aa7b0d7dac5347d16af3f4e5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ondata/ckan-mcp-server","events":[{"introduced":"0"},{"fixed":"3b827af72b228d42aa7b0d7dac5347d16af3f4e5"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.4.112"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.4.108","v0.4.107","v0.4.106","v0.4.105","v0.4.103","v0.4.102","v0.4.101","v0.4.100","v0.4.99","v0.4.98","v0.4.97","v0.4.96","v0.4.95","v0.4.94","v0.4.93","v0.4.92","v0.4.91","v0.4.90","v0.4.89","v0.4.88","v0.4.87","v0.4.86","v0.4.85","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-2026-73844.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
