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 través de la versión 1.5.4, el servidor API de LightRAG se enlaza a todas las interfaces de red con la autenticación deshabilitada por defecto, permitiendo a un atacante de red no autenticado leer el contenido de documentos indexados, cargar o eliminar documentos, modificar el grafo de conocimiento, cancelar pipelines, borrar cachés y consumir recursos de LLM. Este problema se mitiga en la versión 1.5.5rc1."
