How the CVE Works:
CVE-2025-30469 is a lock screen bypass vulnerability in iOS/iPadOS allowing physical attackers to access photos without authentication. The flaw stems from improper state management in the Photos app when handling locked device states. Attackers exploit UI race conditions or cached session data to bypass the lock screen, granting unauthorized access to the photo library. The vulnerability requires physical interaction but no additional execution privileges, making it critical for devices left unattended. Apple patched it in iOS/iPadOS 18.4 by enforcing stricter state validation.
