CVE-2025-43436

Installed-app enumeration via insufficient CoreServices restrictions

Published Nov 4, 2025 · Updated Nov 4, 2025

Information disclosure in CoreServices in Apple iOS and iPadOS, tvOS, visionOS, and watchOS before 26.1 allows apps to enumerate installed apps. CoreServices applies insufficient permission restrictions when an app queries the installed-application inventory; Apple has not disclosed the affected API or exact authorization check. Execution of an app on an affected device is required, and the observed consequence is disclosure of the user's installed-app list rather than access to app data.
