Name of the Vulnerable Software and Affected Versions Vvveb versions prior to 1.0.8.2

Description Vvveb CMS fails to validate the sign of the quantity parameter on the 'cart-add' endpoint. By submitting a negative integer, the server processes it as a normal line-item, causing downstream computations for line totals, sub-totals, taxes, and grand totals to become negative. This allows the checkout flow to accept a negative cart, resulting in orders being saved in the merchant database with a negative total, creating records where the merchant effectively owes the customer money.

Recommendations Update to version 1.0.8.2.
