WP Data Access <= 5.5.7 - Cross-Site Request Forgery

The WP Data Access plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.5.7. This is due to missing or incorrect nonce validation on the backup_page() function. This makes it possible for unauthenticated attackers to trigger backups via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
