⚠️ Risk & Real-World Impact
Worst Case
An attacker with local access gains full administrative control, potentially compromising the entire system, installing malware, or accessing sensitive data.
Likely Case
A malicious insider or compromised low-privilege account escalates to administrator, enabling unauthorized configuration changes or data access.
If Mitigated
With proper access controls and monitoring, exploitation would be detected and contained before significant damage occurs.
