CVE-2026-47741 Details
Description
Shopper is a Headless e-commerce Admin Panel. Prior to 2.8.0, CreateOrderFromCartAction::execute previously created the Order row before checking and incrementing the discount's total_use counter. Under concurrent checkout pressure (Black Friday, flash sale, viral coupon), the global usage_limit was silently exceeded: orders were committed with the discount fully applied to price_amount while the counter blocked at usage_limit. The merchant had no signal that an over-redemption had occurred. This vulnerability is fixed in 2.8.0.
A race condition vulnerability has been identified in Shopper, a headless e-commerce admin panel, prior to version 2.8.0. The issue arises in the CreateOrderFromCartAction::execute method, where the order is created before the discount's usage counter is updated. This flaw allows the global usage limit to be exceeded, particularly during high-traffic events like Black Friday or flash sales. As a result, discounts are applied beyond the intended limit without any notification to the merchant. Additionally, a related issue exists with the per-user usage limit, which is ineffective because the necessary counter is never incremented, leading to potential abuse of discount codes.
Upgrade to Shopper version 2.8.0, which fixes the vulnerability by reserving the discount usage before creating the order, ensuring proper synchronization and validation. After upgrading, run the migration command to apply the necessary database changes.
