Descriptions

In WordPress before 4.7.3, there is cross-site request forgery (CSRF) in Press This (wp-admin/includes/class-wp-press-this.php), leading to excessive use of server resources. The CSRF can trigger an outbound HTTP request for a large file that is then parsed by Press This.

En WordPress en versiones anteriores a 4.7.3, hay CSRF en Press This (wp-admin/includes/class-wp-press-this.php), lo que conduce a un uso excesivo de recursos del servidor. El CSRF puede desencadenar una solicitud HTTP de salida para un archivo grande que luego se analiza mediante Press This.
