Displayed-data disclosure via mishandled temporary files

Published Sep 16, 2024 · Updated Apr 2, 2026

Information disclosure in Shortcuts on Apple iOS, iPadOS, and macOS allows local users to read data displayed to the user. Shortcuts mishandles temporary files so another local app can observe displayed data; Apple has not published the affected path or faulty operation. Execution of an app in a local user context is required, and the documented consequence is disclosure of displayed Shortcuts data only.
