Sensitive user data access via insufficient checks
Published Oct 28, 2024 · Updated Apr 2, 2026
Authorization weakness in Apple DiskArbitration in macOS before 15 and visionOS before 2 allows local users to read sensitive user data. Apple identifies DiskArbitration as the affected component but has not published which authorization check accepts the sandboxed app's request. Exploitation requires local code execution inside an application sandbox; the published consequence is limited to unauthorized access to sensitive user data.
