Account identifier disclosure via insufficient permissions
Published Sep 14, 2026 · Updated Sep 14, 2026
Information disclosure in affected Apple operating systems before 27 or 26.7 allows local apps to read a persistent account identifier. The affected permissions check insufficiently restricts app access to that identifier; Apple has not disclosed the component or API involved. A locally installed app must run on the device, and the documented consequence is identifier disclosure without reported data modification or service interruption.
