Password autofill via failed-authentication state confusion
Published Mar 31, 2025 · Updated Apr 2, 2026
Authentication bypass in Apple operating systems allows attackers to autofill passwords after failed authentication via unspecified vectors. Authentication Services incorrectly preserves or accepts autofill authorization state after authentication fails, although Apple has not disclosed the responsible function or state transition. Reaching the flaw requires an autofill request followed by failed authentication, and the bounded consequence is that a stored password is filled despite the failed check.
