In PrestaShop between versions 1.5.0.0 and 1.7.6.5, there are improper access control since the the version 1.5.0.0 for legacy controllers. - admin-dev/index.php/configure/shop/customer-preferences/ - admin-dev/index.php/improve/international/translations/ - admin-dev/index.php/improve/international/geolocation/ - admin-dev/index.php/improve/international/localization - admin-dev/index.php/configure/advanced/performance - admin-dev/index.php/sell/orders/delivery-slips/ - admin-dev/index.php?controller=AdminStatuses The problem is fixed in 1.7.6.5
In PrestaShop before version 1.7.6.4, when a customer edits their address, they can freely change the id_address in the form, and thus steal someone else's address. It is the same with CustomerForm, you are able to change the id_customer and change all information of all accounts. The problem is patched in version 1.7.6.4.
In PrestaShop 1.7.6.2, XSS can occur during addition or removal of a QuickAccess link. This is related to AdminQuickAccessesController.php, themes/default/template/header.tpl, and themes/new-theme/js/header.js.
