| Description | Unauthenticated TOCTOU Race Condition in OpenCart Checkout allows attackers to bypass business logic, leading to financial loss and inventory corruption. Concurrent requests can successfully apply single-use coupons multiple times (bypassing limits) and simultaneously deduct stock from products, causing negative inventory levels (overselling). This is exploitable via Guest Checkout (PR:N). |
