Descriptions

In Eclipse Vert.x version 3.0 to 3.5.1, the HttpServer response headers and HttpClient request headers do not filter carriage return and line feed characters from the header value. This allow unfiltered values to inject a new header in the client request or server response.

En Eclipse Vert.x, de la versión 3.0 a la 3.5.1, las cabeceras de respuesta HttpServer y las cabeceras de petición HttpClient no filtran los retornos de carro y los caracteres de avance de línea desde el valor de la cabecera. Esto permite que los valores no filtrados inyecten una nueva cabecera en la petición del cliente o la respuesta del servidor.
