Official description

The BackWPup WordPress plugin before 5.7.7 does not verify that a request to its cron-triggered backup execution handler actually originates from WordPress's internal scheduled-event dispatch, allowing unauthenticated attackers to force any existing backup job to run immediately, independent of its configured trigger type or schedule.
