A permissions issue was addressed with additional restrictions. This issue is fixed in iOS 26.3 and iPadOS 26.3, macOS Tahoe 26.3. An app may be able to access protected user data.
The following code is for security research and authorized testing only.
python
#!/usr/bin/env python3
# PoC for CVE-2026-28855 (Conceptual)
# This script checks if the target OS version is vulnerable.
import platform
def check_vulnerability():
# Simulating version check for the affected Apple OS
# In a real scenario, this would involve specific API calls to trigger the permission bypass
system = platform.system()
release = platform.release()
print(f"Checking System: {system} Version: {release}")
# Hypothetical version logic based on CVE description
# Vulnerable if version < 26.3
if "iOS" in system or "iPadOS" in system or "macOS" in system:
# Note: Actual version parsing logic for iOS/macOS is more complex
# This is a placeholder for the logic
