      "value": "Apache CXF allows to set a limit on the number of form parameters in a JAX-RS message via the \"maxFormParameterCount\" configuration option. However, no default limit is set which may lead to denial of service attacks when processing  requests with very large numbers of form parameters. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue by using a default limit of 500 parameters."

      "value": "Apache CXF permite establecer un límite en el número de parámetros de formulario en un mensaje JAX-RS a través de la opción de configuración ’maxFormParameterCount’. Sin embargo, no se establece ningún límite predeterminado, lo que puede llevar a ataques de denegación de servicio al procesar solicitudes con un número muy elevado de parámetros de formulario. Se recomienda a los usuarios actualizar a las versiones 4.2.3 o 4.1.8 o 3.6.12, que solucionan este problema utilizando un límite predeterminado de 500 parámetros."
