CVE-2025-43408

Contact disclosure via locked-device Share Sheet

Published Nov 4, 2025 · Updated Nov 4, 2025

Improper access control in macOS Share Sheet allows physically proximate attackers to access contacts from a locked device. The Share Sheet offers contact-selection options while the device is locked, bypassing the lock screen's intended access restriction. Physical possession of a locked Mac is required, and the published evidence reports contact access only, not contact modification or system unlock.
