CVE-2026-61808 Details
Description
LightRAG provides simple and fast retrieval-augmented generation. Through version 1.5.4, the LightRAG API server binds to all network interfaces with authentication disabled by default, allowing an unauthenticated network attacker to read indexed document content, upload or delete documents, modify the knowledge graph, cancel pipelines, clear caches, and consume LLM resources. This issue is mitigated in version 1.5.5rc1.
A vulnerability exists in the LightRAG API server in versions through 1.5.4, where the server binds to all network interfaces without authentication. This allows unauthenticated attackers to access sensitive API functions. The issue is particularly concerning because the server is exposed to the network by default, creating a significant security risk. The vulnerability arises from an intentional design choice to facilitate local development, but it can have serious consequences when the server is deployed in a production environment.
Users should update to LightRAG version 1.5.5 or later, and configure authentication by setting the 'LIGHTRAG_API_KEY' or 'AUTH_ACCOUNTS' with a non-default 'TOKEN_SECRET'. For local-only access, bind the server to '127.0.0.1'.
