Esto permitir\u00eda que una parte malintencionada intentara manipular el LLM para producir un payload malicioso para el analizador que comprometer\u00eda la disponibilidad del servicio. Un ataque exitoso se basa en: 1. Uso de XMLOutputParser 2. Pasar entradas maliciosas al XMLOutputParser, ya sea directamente o intentando manipular un LLM para que lo haga en nombre del usuario 3. Exponer el componente a trav\u00e9s de un servicio web"
