⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where attackers gain administrative privileges, create persistent backdoor accounts, access sensitive data, modify system configurations, and potentially pivot to other systems.
Likely Case
Attackers gain administrative access, create new admin accounts for persistence, access ticket data and user information, and potentially modify system settings.
If Mitigated
With proper server-side authorization checks, regular users remain limited to their assigned privileges with no ability to escalate.
🎯 Exploit Status
Requires authenticated user access but exploitation is straightforward once authenticated.
🛠️ Fix & Mitigation
