CVE-2023-42930

Protected file-system modification by local apps

Published Mar 28, 2024 · Updated Nov 4, 2025

A Shell flaw in Apple macOS before 12.7.2, 13.6.3, and 14.2 allows local users to modify protected parts of the file system. Apple has not published the nature of the failed checks or identified the Shell code path that improperly accepts an app’s file-system operation. Reaching the flaw requires a locally run app and user interaction; the documented consequence is modification of protected file-system content, not disclosure or service interruption.
