AI risk analysis

Summary: The LightRAG login endpoint lacks rate limiting, allowing attackers to perform brute-force password guessing attacks, which can lead to unauthorized access to sensitive documents and administrative operations.
Exploitability: Exploitation is relatively easy given full request speed access, requiring only network connectivity and knowledge of the endpoint.
Blast radius: If exploited, this can result in unauthorized access to sensitive data and administrative functions, potentially leading to significant data breaches.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to version 1.5.5 or later.

NVD description

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.5, the POST /login endpoint in lightrag/api/lightrag_server.py does not impose a rate limit, account lockout, delay, or counter for failed authentication attempts. A network attacker can submit password guesses at full request speed until a valid account password is found. Successful credential recovery grants authenticated access to documents, the knowledge graph, and administrative operations. This issue is fixed in version 1.5.5.
