⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data manipulation, or full system takeover via SQL command execution.
Likely Case
Unauthorized data access, data exfiltration, or database manipulation leading to information disclosure.
If Mitigated
Limited impact due to proper input validation, parameterized queries, or database permissions restricting SQL execution.
🎯 Exploit Status
SQL injection vulnerabilities typically have low exploitation complexity when unauthenticated access is possible.
