CVE-2026-28863 Apple多系统权限绕过致用户指纹识别

// Conceptual PoC for Device Fingerprinting via Permission Bypass // This code simulates an app accessing device info that should be restricted #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> int main(int argc, char * argv[]) { @autoreleasepool { // Simulate accessing restricted device info NSString *deviceModel = [[UIDevice currentDevice] model]; NSString *systemVersion = [[UIDevice currentDevice] systemVersion]; // Hypothetical access to a restricted identifier or system feature // that was supposed to be blocked in older versions NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSDictionary *fingerprintData = @{ @"model": deviceModel, @"os": systemVersion, @"restricted_access": @"success" // Proof of bypass }; NSLog(@"Fingerprint Data: %@", fingerprintData); // In a real exploit, this data would be exfiltrated to a remote server } return 0; }
