Miggo AIRoot Cause Analysis

The key vulnerability stems from how user-supplied data (album names, descriptions) was retrieved and output without adequate escaping. The patch adds 'database' format parameter to getValue() calls in photo_album_new.php, which correlates with changes in TablePhotos::getValue where format handling occurs. The removed global $gL10n and added format checks indicate the method previously returned raw database values without context-aware escaping. When called without the 'database' format (as in pre-patch code), the method failed to neutralize HTML-sensitive characters in these fields, enabling stored XSS payloads to execute when rendered in admin UI components.
