The issue was addressed with improved checks. This issue is fixed in iOS 18.7.2 and iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1. An app may be able to monitor keystrokes without user permission.
The following code is for security research and authorized testing only.
python
// CVE-2025-43495 PoC - Conceptual Proof of Concept
// Note: This is a conceptual example for educational purposes only
import Foundation
class KeystrokeMonitor {
// This PoC demonstrates the vulnerability concept
// In vulnerable versions, this could capture keystrokes without permission
func attemptKeystrokeCapture() -> Bool {
// Vulnerable code pattern - accessing input without proper checks
let inputMonitor = CGEventSource(nil)
// Attempt to register for input events
// In vulnerable versions, this may succeed without user consent
let eventMask = (1 << CGEventType.keyDown.rawValue) |
(1 << CGEventType.keyUp.rawValue)
// Simulated keystroke capture attempt
print("Attempting to monitor keystrokes...")
print("Vulnerable system may allow this without permission prompt")
return true
}
}
// Mitigation: Update to iOS 18.7.2/iPadOS 18.7.2 or later
// iOS 26.1/iPadOS 26.1 or later
// Security checks that should be implemented:
func verifyInputMonitoringPermission() -> Bool {
// After patch, proper permission check is required
// Application must request and receive user authorization
// before accessing any keyboard input events
return checkEntitlement("com.apple.security.keyboard-monitoring")
