Descriptions

The POST SMTP Mailer WordPress plugin before 2.5.7 does not have proper CSRF checks in some AJAX actions, which could allow attackers to make logged in users with the manage_postman_smtp capability resend an email to an arbitrary address (for example a password reset email could be resent to an attacker controlled email, and allow them to take over an account).

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 resend_email() function. This makes it possible for unauthenticated attackers to resend emails to an arbitrary email address via a forged request granted they can trick a site user with the manage_postman_smtp capability into performing an action such as clicking on a link. An attacker could leverage this to resend a password reset email to their own account and compromise a site administrators account.
