Grav versions before 2.0.13 fail to properly validate backup profile root paths, allowing attackers to archive directories outside GRAV_ROOT when not in the hard-coded deny-list. Attackers with profile editor access can configure backup profiles with traversal paths to expose sensitive files from locations like /opt, /mnt, or /srv.
