Shopware is an open source commerce platform based on Symfony Framework and Vue js. In affected versions It was possible to put the same line item multiple times in the cart using the AP. The Cart Validators checked the line item’s individuality and the user was able to bypass quantity limits in sales. This problem has been fixed with version 220.127.116.11. Users on major versions 6.1, 6.2, and 6.3 may also obtain this fix via a plugin.
