      "value": "Microsoft UFO open-source framework for intelligent automation across devices and platforms. In 3.0.1-4-ge2626659, Microsoft UFO accepts client-supplied session_id values in WebSocket task messages and reuses an existing in-memory session object if that session_id already exists. If a prior session has completed and remains in memory with populated results, a different authenticated client can send a new TASK message using the same session_id. The server re-enters the existing session object and sends the stale stored result to the new requester through the normal send_task_end() callback path. This is an authenticated cross-client stale result replay issue. The issue requires that the attacker knows or can predict a live or recently completed session_id."

      "value": "Microsoft UFO framework de código abierto para automatización inteligente en todos los dispositivos y plataformas. En 3.0.1-4-ge2626659, Microsoft UFO acepta valores de session_id proporcionados por el cliente en mensajes de tarea de WebSocket y reutiliza un objeto de sesión existente en memoria si ese session_id ya existe. Si una sesión anterior ha completado y permanece en memoria con resultados poblados, un cliente autenticado diferente puede enviar un nuevo mensaje TASK usando el mismo session_id. El servidor vuelve a entrar en el objeto de sesión existente y envía el resultado obsoleto almacenado al nuevo solicitante a través de la ruta de callback normal de send_task_end(). Este es un problema autenticado de repetición de resultados obsoletos entre clientes. El problema requiere que el atacante conozca o pueda predecir un session_id activo o recientemente completado."
