CVE-2026-86815: BackWPup limited roles can exfiltrate database backups

BackWPup before 5.7.5 does not properly restrict several REST API routes used to manage jobs, backup destinations, and backup execution. A user holding a limited BackWPup role assigned by an administrator can create and run a backup job, direct the resulting full database backup to an attacker-controlled destination, and exfiltrate site data. The authoritative export does not name the individual routes, parameters, or permission callbacks.
