In the AccessAlly WordPress plugin before 3.5.7, 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.
