CVE-2024-54530Network attack vector

Unauthorized password autofill via failed authentication checks

Published Jan 27, 2025 · Updated Jun 2, 2026

Incorrect authorization in iOS, iPadOS, macOS, visionOS, and watchOS allows attackers to autofill passwords after failed authentication. The Passkeys component inadequately checks the result of an authentication attempt before permitting password autofill; Apple has not disclosed the specific check or request path. CISA assesses network reachability without prior privileges or user interaction; the documented consequence is unauthorized autofill of stored passwords.
