This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to send arbitrary newsletter emails to users of any WordPress role, including administrators, by forging POST fields during a normal post submission. This allows an attacker-supplied role slug via the newsletters_mailinglistsroles POST field to be passed directly to get_users(), enabling unauthorized mass-mailing and potential phishing against privileged site users through the site's own outbound email channel."}, {"lang": "es", "value": "El plugin Newsletters para WordPress es vulnerable a un bypass de autorizaci\u00f3n en todas las versiones hasta la 4.17, inclusive.
