Summary
In Apache Tika 1.19 (CVE-2018-11761), we added an entity expansion limit for XML parsing. However, Tika reuses SAXParsers and calls reset() after each parse, which, for Xerces2 parsers, as per the documentation, removes the user-specified SecurityManager and thus removes entity expansion limits after the first parse. Apache Tika versions from 0.1 to 1.19 are therefore still vulnerable to entity expansions which can lead to a denial of service attack. Users should upgrade to 1.19.1 or later.

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). Los usuarios deber\u00edan actualizar a la versi\u00f3n 1.19.1 o posteriores."
