⚠️ Risk & Real-World Impact
Worst Case
A local attacker gains full root privileges on the macOS system, enabling complete system compromise, data theft, persistence installation, and lateral movement.
Likely Case
Local privilege escalation allowing attackers to bypass security controls, install malware, or access sensitive data they wouldn't normally have permission to access.
If Mitigated
Limited impact with proper privilege separation and monitoring in place, though local users could still gain elevated privileges.
🎯 Exploit Status
Exploitation requires local access but appears to be straightforward based on the CWE-226 (Sensitive Information in Resource Not Removed Before Reuse) classification.
