Unauthenticated state manipulation via exposed Socket.IO handlers
Published Feb 2, 2026 · Updated Feb 2, 2026
Improper access control in ParisNeo LoLLMS allows remote attackers to invoke sensitive Socket.IO generation events without authentication. The add_events function in lollms_generation_events.py registers generate_text, cancel_generation, generate_msg, and generate_msg_from handlers without authentication or authorization checks. Any network client that can reach the Socket.IO service can consume generation resources, cancel another client's work, or corrupt shared state through global busy and cancellation flags.
