Team data deletion via missing owner check
Published Aug 26, 2026 · Updated Aug 26, 2026
Improper authorization in Midday allows remote authenticated users with team membership to delete their team and all data scoped to it. At commit e5f45ed0d49cdb34576373623c4579b72daa74c1, the team.delete tRPC procedure uses hasTeamAccess, which verifies membership but not the owner role, before calling the deletion and cleanup paths. Any invited member can therefore destroy team records and initiate connected-bank cleanup; no unauthenticated access is exposed.
