Installed-app enumeration via LaunchServices permissions issue

Published Aug 25, 2026 · Updated Aug 25, 2026

A permissions issue in LaunchServices in Apple iOS and iPadOS before 26.5 allows local users to enumerate installed apps through a malicious app. Apple identifies the component and a permissions failure but has not disclosed the specific API or missing authorization check. Execution of an attacker-controlled app on a supported iPhone or iPad is required, and the reported consequence is limited to learning which apps are installed.
