Technical details
CVE-2026-86893 is a permissions issue in Apple's CloudKit framework where an app may read device name information despite insufficient authorization controls. The vulnerability stems from inadequate state management in the permissions mechanism protecting CloudKit's device name metadata. No authentication bypass is required—any app can trigger this disclosure through normal CloudKit API calls. The attack is local and does not require user interaction beyond installing the app. Apple addressed this issue by implementing additional access restrictions to the CloudKit permissions model, preventing unauthorized device name disclosure.
