Medium (4.3) in wp-mpdf project wp-mpdf. EPSS 0.4% chance of exploitation in the next 30 days.
The wp-mpdf plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.5.1. This is due to missing or incorrect nonce validation on the mpdf_admin_savepost() function. This makes it possible for unauthenticated attackers to save post data via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
