{"cve":"CVE-2026-85709","nvd":{"published":"2026-09-22T17:17:27.020","modified":"2026-09-22T19:16:54.750","status":"Deferred","description":"LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.5, the LightRAG API server returns raw Python exception text from error handlers in document_routes.py, graph_routes.py, query_routes.py, ollama_api.py, and lightrag_server.py. The detail=str(e), detail=str(exc), and equivalent formatted-message paths expose server filesystem paths, database host, port, user, and database names, language-model provider diagnostics, configuration details, and Python library internals to a network client that can trigger an error. The default unauthenticated configuration makes those responses reachable without credentials, and URI-configured backends can disclose connection strings containing credentials depending on the underlying driver error. This issue is fixed in version 1.5.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-209"],"references":["https://github.com/HKUDS/LightRAG/commit/4d90a0eb35d40b45f3a9045e308ec126897a3364","https://github.com/HKUDS/LightRAG/commit/dcab315d7dc1eea682e9b2c4fcb1b06474484c47","https://github.com/HKUDS/LightRAG/pull/3422","https://github.com/HKUDS/LightRAG/releases/tag/v1.5.5","https://github.com/HKUDS/LightRAG/security/advisories/GHSA-hrmj-7rvj-4hg8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-85709","score":0.00419,"percentile":0.36264,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hrmj-7rvj-4hg8","url":"https://osv.dev/vulnerability/GHSA-hrmj-7rvj-4hg8","summary":"lightrag-hku: Sensitive Information Exposure Through Raw Exception Messages in API Error Responses","modified":"2026-10-01T17:56:20.307861213Z","packages":[{"ecosystem":"PyPI","name":"lightrag-hku","purl":"pkg:pypi/lightrag-hku","ranges":["<1.5.5"],"fixed":["1.5.5"]}]},{"id":"PYSEC-2026-4063","url":"https://osv.dev/vulnerability/PYSEC-2026-4063","summary":"lightrag-hku: Sensitive Information Exposure Through Raw Exception Messages in API Error Responses","modified":"2026-10-01T17:45:05.567981287Z","packages":[{"ecosystem":"PyPI","name":"lightrag-hku","purl":"pkg:pypi/lightrag-hku","ranges":["<1.5.5"],"fixed":["1.5.5"]}]}],"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).
