⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains SYSTEM/root privileges on the affected system, enabling complete system compromise, data theft, and persistence.
Likely Case
Local authenticated users (including low-privilege accounts) elevate to administrative privileges, potentially installing malware or accessing sensitive data.
If Mitigated
With proper access controls and least privilege principles, impact is limited to the user's own session and data.
🎯 Exploit Status
Exploitation requires authenticated local access. The CWE-20 (Improper Input Validation) suggests straightforward exploitation once the vulnerable input vector is identified.
