Private-tab disclosure via flawed authentication state management

Published Sep 16, 2024 · Updated Apr 2, 2026

Authentication bypass in Apple Safari Private Browsing before 18 allows attackers to access private tabs without authentication. Apple states that Safari Private Browsing mishandles authentication state but has not disclosed the affected function or incorrect state transition. No additional access precondition is publicly disclosed; the bounded consequence is viewing existing Private Browsing tabs.
