Keep Backup Daily plugin for WordPress before 2.1.4 contains a sensitive information exposure vulnerability that allows unauthenticated attackers to trigger a full MySQL database dump by accessing the publicly exposed `kbd_cron_process` parameter without authentication. Attackers can predict the partially predictable dump filename based on the database name, a limited random range, and the current Unix timestamp to download the generated backup from the publicly accessible uploads directory.
