AccessAlly < 3.5.7 - $_SERVER Superglobal Leakage

In the plugin, the file “resource/frontend/product/product-shortcode.php” responsible for the [accessally_order_form] shortcode is dumping serialize($_SERVER), which contains all environment variables. The leakage occurs on all public facing pages containing the [accessally_order_form] shortcode, no login or administrator role is required. AccessAlly 3.5.7 resolved the issue.
