The Total Upkeep – WordPress Backup Plugin plus Restore & Migrate by BoldGrid plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'wp_ajax_cli_cancel' function in all versions up to, and including, 1.17.1. This makes it possible for unauthenticated attackers to cancel a pending rollback, potentially preventing a WordPress installation from automatically reverting a failed update.
