CVE-2023-32376

Protected file modification via insufficient entitlements

Published Jun 23, 2023 · Updated Dec 5, 2024

Improper authorization in StorageKit in Apple operating systems allows local users to modify protected file-system areas through an app. StorageKit applies insufficient entitlements to the app's file-system operations, allowing writes beyond its authorized storage boundary. Execution of a crafted local app with user interaction is required; the disclosed consequence is unauthorized file modification, not code execution.
