Unauthorized cart price changes via offer form
Published Sep 3, 2026 · Updated Sep 3, 2026
Missing authorization in WPFunnels 3.12.13 and earlier allows remote attackers to add products at requester-controlled prices. The offer payment form trusts a requester-supplied product price when adding an item to the WooCommerce cart instead of enforcing configured pricing. No WordPress account is required, so arbitrary price reductions can alter cart and order values before checkout without user interaction.
