Summary

Allegro Ralph through 20260902.1 has a missing authorization flaw (CWE-862) that lets authenticated staff users bypass rack model permissions. RalphPermission skips checks for views without a queryset, so DCAssetsView and SRRacksAPIView are reachable at /api/rack/<id> and /api/server_room/<id>. An attacker can read asset hostnames, serials and management IPs, and can modify, move or create racks.
