MEDIUM 5.3

LightRAG: Sensitive Information Exposure Through Raw Exception Messages in API Error Responses

CVSS Score
5.3
EPSS Score
0.0%
EPSS Percentile
0th

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.
