Sin embargo, Tika reutiliza SAXParsers y llama a reset() tras cada an\u00e1lisis y, en el caso de los analizadores Xerces2, tal y como se indica en la documentaci\u00f3n, elimina el SecurityManager especificado por el usuario y elimina los l\u00edmites de expansi\u00f3n de entidades tras el primer an\u00e1lisis. Por lo tanto, las versiones de la 0.1 a la 1.19 de Apache Tika siguen siendo vulnerables a expansiones de entidades, lo que podr\u00eda conducir a un ataque de denegaci\u00f3n de servicio (DoS).
