Cart calculation manipulation via client-supplied measurement units
Published Sep 11, 2026 · Updated Sep 11, 2026
Broken access control in Flexible Quantity 2.3.21 and earlier allows remote attackers to alter cart calculations via add-to-cart requests. The add-to-cart path trusts a client-supplied measurement unit instead of the product template's pricing unit when calculating price, inventory, and shipping. No authentication is required; a crafted request can make WooCommerce apply attacker-selected units to cart pricing, stock accounting, and shipping calculations.
