Miggo AIRoot Cause Analysis

The commit diff shows a critical change in BcAdminFormHelper.php where 'escape' => true was added to the 'figcaption' configuration. This indicates the XSS vulnerability stemmed from unescaped output in the figcaption element generated by the control() method when handling file uploads. The helper's role in form rendering and the explicit addition of escaping in the patch directly correlate to the described Content Management XSS vulnerability.
