What it is

Fleet versions before 4.89.0 fail to properly filter MDM command results by team authorization in the commands/results endpoint. Team-scoped users can read MDM command results for hosts on other teams when a shared command UUID targets hosts across multiple teams, exposing host UUIDs, command payloads, and device responses.
