relevant fixed versions and status.
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.
