How the Mentioned CVE Works:
CVE-2025-24115 is a critical vulnerability in macOS that allows a malicious application to bypass sandbox restrictions and access files outside its designated environment. This occurs due to improper path validation in the operating system, enabling an app to exploit this flaw and read sensitive data from unauthorized directories. The issue affects macOS Ventura 13.7.3, macOS Sequoia 15.3, and macOS Sonoma 14.7.3. Apple addressed this vulnerability by improving path validation mechanisms in subsequent updates. The CVSS 4.0 score reflects its critical severity due to the potential for unauthorized data access and system compromise.

- An attacker crafts a malicious app with improper path handling.
- The app exploits the flawed validation to access files outside its sandbox.
3. Sensitive data is exfiltrated or modified.
Protection:
1. Update macOS to the latest version.
- Use app sandboxing policies to restrict file access.
- Monitor app behavior for unusual file access patterns.
Commands:
1. Check macOS version:
sw_vers
2. Update macOS:
softwareupdate --install --all
Code Snippet (Detection):
import os
def check_sandbox_access(app_path):
if os.path.exists(app_path):
print("Potential sandbox escape detected.")
