Miggo AIRoot Cause Analysis

The vulnerability stems from unsanitized user input in username fields being stored and displayed in admin logs. The commit diff shows the fix added htmlspecialchars(stripslashes()) around $record['field_1'] in datatable.logs.php, confirming the missing output encoding was the vulnerability point. The affected code constructs CSV log entries that get rendered as HTML tables, making this the precise XSS injection vector.
