WP Database Backup <= 4.3.5 - Cross-Site Request Forgery
The WP Database Backup plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.3.5. This is due to missing or incorrect nonce validation on the wp_db_backup_admin_init() function. This makes it possible for unauthenticated attackers to modify backups via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
