Miggo AIRoot Cause Analysis

The vulnerability stems from inline PHP code in 'userfiles/modules/admin/notifications/notif_form_entry.php' that directly outputs user-controlled data ($val1 and $val1_1) using print statements without proper escaping. While no named functions are involved, the lack of output sanitization (via htmlentities) in these template rendering lines allowed stored XSS. The patch added escaping to these print statements, confirming the vulnerability was in raw output handling rather than specific functions.
