Researcher Erwan LR - WPScan

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 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.
