EmbedPress < 3.8.4 - Cross-Site Request Forgery

Description

The EmbedPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.8.3. This is due to missing nonce validation on the clicked() function. This makes it possible for unauthenticated attackers to trigger notice clicks via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
