Persistent device identifier disclosure via access-control bypass
Published Sep 14, 2026 · Updated Sep 14, 2026
Authorization bypass in Apple DeviceCheck across iOS, iPadOS, macOS, tvOS, visionOS, and watchOS releases allows local apps to read device IDs. DeviceCheck applies insufficient access control when an app requests persistent device identifiers, allowing the request to return identifiers that should be restricted. Exploitation requires locally executing app code and exposes persistent identifiers; Apple has not disclosed further implementation details.
