⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root-level code execution, data theft, and persistent backdoor installation
Likely Case
Local privilege escalation allowing attackers to execute arbitrary code with elevated permissions
If Mitigated
Limited impact if proper access controls and isolation are in place, but still significant risk
🎯 Exploit Status
Requires local access to the system. CWE-863 indicates incorrect authorization, suggesting authentication bypass or privilege escalation vectors.
🛠️ Fix & Mitigation
