What is CVE-2025-3743?

The Upsell Funnel Builder for WooCommerce plugin for WordPress is susceptible to order manipulation due to inadequate validation of user inputs. This vulnerability allows unauthenticated attackers to exploit the 'add_offer_in_cart' function, which permits editing the product ID and discount fields before order processing. Consequently, attackers can arbitrarily adjust the product associated with any order bump and modify the discount applied, posing a significant risk to the integrity of online transactions.

Affected Version(s)

Upsell Funnel Builder for WooCommerce – Create Upsells, Cross-Sells, Order Bumps, Frequently Bought, and Popups. 0 <= 3.0.0
