CVE-2024-23277Network attack vector

Keystroke injection via spoofed Bluetooth keyboard

Published Mar 8, 2024 · Updated Apr 2, 2026

Bluetooth input validation in iOS and iPadOS before 17.4 and macOS before 14.4 allows remote attackers to inject spoofed keystrokes. The Bluetooth component accepts keyboard events from a spoofed device; Apple has not disclosed which validation operation fails. The attacker must hold a privileged network position; successful spoofing lets forged key events control the active device interface.
