CVE-2025-3743: CWE-472 External Control of Assumed-Immutable Web Parameter in wpswings Upsell Funnel Builder for WooCommerce – Create Upsells, Cross-Sells, Order Bumps, Frequently Bought, and Popups.
The Upsell Funnel Builder for WooCommerce plugin for WordPress is vulnerable to order manipulation in all versions up to, and including, 3.0.0. This is due to the plugin allowing the additional product ID and discount field to be manipulated prior to processing via the 'add_offer_in_cart' function. This makes it possible for unauthenticated attackers to arbitrarily update the product associated with any order bump, and arbitrarily update the discount applied to any order bump item, when adding it to the cart.
AI Analysis
Technical Summary
The Upsell Funnel Builder for WooCommerce plugin suffers from an external control of assumed-immutable web parameters (CWE-472). Specifically, the plugin's 'add_offer_in_cart' function does not properly validate the additional product ID and discount fields, allowing unauthenticated attackers to modify these parameters arbitrarily. This manipulation can change the product associated with any order bump and the discount applied to it when added to the cart. The vulnerability affects all versions up to and including 3.0.0. The CVSS 3.1 base score is 5.3 (medium), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, no confidentiality or availability impact, but integrity impact is low.
Potential Impact
An attacker can alter the product and discount values for order bumps in the shopping cart without authentication. This could lead to unauthorized discounts or substitution of products in upsell offers, potentially causing financial loss or order manipulation. There is no impact on confidentiality or availability reported. No known exploitation in the wild has been documented.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch links or official fixes are provided, users should monitor the vendor's communications for updates. Until a fix is available, consider disabling the Upsell Funnel Builder plugin or restricting access to its functionality to trusted users only to reduce exposure.
