Official description

Allegro Ralph through 20260902.1 contains a missing authorization vulnerability that allows authenticated staff users to bypass rack model permissions because RalphPermission skips checks for views without a queryset. Attackers can call DCAssetsView and SRRacksAPIView at /api/rack/<id> and /api/server_room/<id> to read asset hostnames, serials and management IPs, and to modify, move or create racks.
