Sensitive data access via faulty state management
Published Sep 14, 2026 · Updated Sep 14, 2026
Authorization failure in Apple macOS before 15.8, 26.7, or 27 allows local users to access sensitive user data through an app. Apple attributes the flaw to faulty state management but has not disclosed the affected component or the authorization decision performed incorrectly. Exploitation requires local app execution, and the documented consequence is limited to unauthorized reading of sensitive user data.
