CVE-2026-78137Network attack vectorHinoki check available

Checkout price manipulation via client-supplied offer price

Published Aug 27, 2026 · Updated Aug 27, 2026

Price manipulation in weDevs StoreGrowth before 2.1.2 allows remote attackers to alter checkout totals through BOGO add-to-cart actions. The BOGO and Upsell Order Bump add-to-cart handlers trust a browser-supplied offer price instead of deriving it from saved offer configuration. A reachable WooCommerce store must have the BOGO offer feature enabled; a crafted cart request then carries the chosen product price into checkout.
