CVE-2023-42850

Sensitive-data access via flawed LaunchServices permissions

Published Oct 25, 2023 · Updated Feb 13, 2025

Incorrect permissions logic in LaunchServices in Apple macOS Sonoma 14.0 allows local users to access sensitive user data through an app. LaunchServices applies insufficient permission restrictions when an app requests user-sensitive data; Apple has not disclosed the exact operation. Exploitation requires a locally launched app and user interaction, and the documented consequence is disclosure without integrity or availability impact.
