{"id":"CVE-2026-85709","published":"2026-09-22T17:17:27.020","lastModified":"2026-09-22T19:16:54.750","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.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-209"],"vendors":[],"products":[],"references":[{"url":"https://github.com/HKUDS/LightRAG/commit/4d90a0eb35d40b45f3a9045e308ec126897a3364","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/commit/dcab315d7dc1eea682e9b2c4fcb1b06474484c47","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/pull/3422","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/releases/tag/v1.5.5","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/security/advisories/GHSA-hrmj-7rvj-4hg8","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/security/advisories/GHSA-hrmj-7rvj-4hg8","tags":[]}],"exploitRefs":[{"url":"https://github.com/HKUDS/LightRAG/commit/4d90a0eb35d40b45f3a9045e308ec126897a3364","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/commit/dcab315d7dc1eea682e9b2c4fcb1b06474484c47","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/pull/3422","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/releases/tag/v1.5.5","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/security/advisories/GHSA-hrmj-7rvj-4hg8","tags":[]},{"url":"https://github.com/HKUDS/LightRAG/security/advisories/GHSA-hrmj-7rvj-4hg8","tags":[]}],"hasPoc":true,"ai":null}
