Event Tickets < 5.11.0.5 - Cross-Site Request Forgery

Description

The Event Tickets plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.11.0.4. This is due to missing or incorrect nonce validation on the handle_action_disconnect() function. This makes it possible for unauthenticated attackers to disconnect a merchant via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
