Privacy preference bypass via faulty TCC state management
Published Sep 8, 2021 · Updated Aug 3, 2024
Logic flaw in Apple TCC in iOS before 14.7 and macOS before 11.5 allows attackers to bypass certain Privacy preferences via a malicious application. Apple identifies faulty TCC state management but has not disclosed the affected state transition or how an application defeats the configured privacy decision. Exploitation requires a malicious application to run on the device, and the bounded consequence is access blocked by the affected preference.
