🔍 How to Verify
Check if Vulnerable:
Check if Lexiglot version is 2014-11-20 or earlier in admin panel or source codeCheck Version:
Check Lexiglot version in admin interface or review source code version markersVerify Fix Applied:
Test admin.php?page=users&from_id= and admin.php?page=history&limit= endpoints with SQL injection payloads📡 Detection & Monitoring
Log Indicators:
- SQL error messages in logs
