⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, modification, deletion, or potential remote code execution if database configuration permits.
Likely Case
Unauthorized access to sensitive application data stored in the database, potentially including user credentials, personal information, or business data.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permission restrictions in place.
🎯 Exploit Status
Exploitation requires understanding of the application's database structure and SQL syntax, but no authentication is needed to trigger the vulnerable endpoint.
