Summary
9Router through version 0.4.41 contain an unauthenticated information disclosure vulnerability that allows remote attackers to access sensitive user data by sending requests to unprotected API endpoints. Attackers can enumerate paginated request logs and retrieve complete AI conversation histories including system prompts, user messages, assistant responses, tool calls, and user email addresses by querying the request-logs and request-details API routes which lack authentication middleware.
