Description

The Essential Blocks for Gutenberg plugin for WordPress is vulnerable to authorization bypass due to incorrectly defined capability checks throughout the 'EB_Openverse_Ajax' class in versions up to, and including, 3.8.5. This makes it possible for unauthenticated attackers to register Openverse clients, upload images, and perform other Openverse actions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
