Network traffic alteration via cleartext Passwords transport

Published Dec 11, 2024 · Updated Apr 2, 2026

Cleartext transport in Passwords in Apple iOS, iPadOS, macOS, and visionOS allows man-in-the-middle attackers to alter network traffic. The component sends information over HTTP rather than HTTPS, permitting an on-path party to modify the exchange in transit. Exploitation requires a privileged network position; Apple has not disclosed the affected endpoint, data, or resulting application behavior.
