Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Fleet (Go module github.com/fleetdm/fleet/v4) versions before 4.84.2 are vulnerable. An authenticated user with the Observer role could abuse the Apple MDM commands listing endpoint's unvalidated ORDER BY parameter and cursor-based pagination to extract values such as host enrollment secrets and APNS tokens one character at a time. Upgrade to version 4.84.2 or later. Until then, restrict the Observer role to fully trusted users and rotate node keys for any host that may have been exposed.
