⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation leading to full system compromise, sensitive data exposure, or credential theft from system files.
Likely Case
Unauthorized reading of sensitive configuration files, user data, or system information accessible to the user account.
If Mitigated
Limited impact if proper access controls and file permissions restrict sensitive data access.
🎯 Exploit Status
Requires local access and user account. Path traversal vulnerabilities typically have low exploitation complexity once access is obtained.
