CVE-2026-79630Network attack vectorHinoki check available

Unauthenticated price manipulation via order-bump product substitution

Published Sep 4, 2026 · Updated Sep 4, 2026

Authorization bypass in WPFunnels before 3.13.0 allows remote attackers to purchase products with unintended order-bump discounts. The checkout order-bump handler accepts a requester-controlled product ID without verifying that it matches the product configured for the discount. No authentication is required; successful abuse carries the substituted discount into the placed order total, reducing the amount charged for any purchasable product.
