"value": "XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible."

"value": "XStream es una biblioteca java de c\u00f3digo abierto para serializar objetos a XML y viceversa. Las versiones anteriores a 1.4.19, pueden permitir a un atacante remoto asignar el 100% del tiempo de la CPU en el sistema de destino, dependiendo del tipo de CPU o de la ejecuci\u00f3n en paralelo de dicha carga \u00fatil, resultando en una denegaci\u00f3n de servicio \u00fanicamente mediante la manipulaci\u00f3n del flujo de entrada procesado. XStream versi\u00f3n 1.4.19 monitoriza y acumula el tiempo que tarda en a\u00f1adir elementos a las colecciones y lanza una excepci\u00f3n si es superado un umbral establecido. Se recomienda a usuarios que actualicen lo antes posible. Los usuarios que no puedan actualizar pueden establecer el modo NO_REFERENCE para impedir una recursi\u00f3n. Ver GHSA-rmr5-cpv2-vgjf para m\u00e1s detalles sobre una medida de mitigaci\u00f3n adicional si una actualizaci\u00f3n no es posible"
