Physical contact disclosure via lock-screen state flaw
Published Feb 27, 2020 · Updated Aug 4, 2024
Information disclosure in the Phone component of Apple iOS before 13.3.1 allows physically proximate attackers to access locked-device contacts. The Phone lock screen applies inconsistent state management, leaving contact data reachable while the device remains locked. Exploitation requires physical possession of a locked device and exposes contacts without reported ability to modify data or disrupt service.
