⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to access administrative functions, modify critical data, or escalate privileges to full system control.
Likely Case
Unauthorized access to sensitive business data, user information, or application functionality beyond intended permissions.
If Mitigated
Limited impact with proper input validation and authorization checks in place, potentially only exposing non-critical functions.
🎯 Exploit Status
