Email Templates < 1.4.3 - Email Sending via CSRF

Description The plugin is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.4.2. This is due to missing or incorrect nonce validation on the send_test_email function. This makes it possible for unauthenticated attackers to send test emails via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
