Descriptions

curl before version 7.51.0 doesn't parse the authority component of the URL correctly when the host name part ends with a '#' character, and could instead be tricked into connecting to a different host. This may have security implications if you for example use an URL parser that follows the RFC to check for allowed domains before using curl to request them.

curl en versiones anteriores a la 7.51.0 no analiza el componente authority de la URL correctamente cuando el nombre del host termina con un carácter "#" y podría conectarse a un host diferente. Esto podría tener implicaciones de seguridad si, por ejemplo, se emplea un analizador URL que sigue el RFC para buscar dominios permitidos antes de emplear curl para solicitarlos.
