Miggo AIRoot Cause Analysis

The vulnerability stems from unescaped output of user-controllable parameters (admin_username and admin_password) in the installation form template (config-form.html). The commit diff explicitly shows the addition of htmlspecialchars() to these echo statements in the patched version, confirming that the lack of output encoding in the original code allowed XSS payloads to render in the browser. These echo statements are the direct points of vulnerability.
