What it is

The BackWPup WordPress plugin before 5.7.5 does not properly restrict access to several of its REST API routes for job, backup-destination, and backup-execution management, allowing users holding a BackWPup WordPress plugin before 5.7.5-defined, administrator-assigned limited role to create and run backup jobs and exfiltrate a full database backup to an attacker-controlled destination.
