Description
The POST SMTP Mailer plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.5.6. This is due to incorrect nonce validation on the delete_logs_ajax() function. This makes it possible for unauthenticated attackers to delete logs granted they can trick a site user with the manage_postman_smtp capability into performing an action such as clicking on a link.
