Does this matter?
Lower severity and a low EPSS score (2.20%). Track it; it rarely justifies an emergency change on its own.
Description
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.
