CVE-2023-35983

Protected filesystem modification by local apps

Published Jul 26, 2023 · Updated Oct 29, 2024

Incorrect authorization in macOS before 11.7.9, 12.6.8, or 13.5 allows local users to modify protected file-system areas. The Assets component applies inadequate data protection, but Apple has not disclosed the affected operation or how untrusted app input reaches it. Exploitation requires a local app and user interaction; the documented consequence is unauthorized file-system modification without confidentiality or availability impact.
