CVE-2026-103329 Details
Description
The Super Payments WordPress plugin before 1.43.1 does not properly verify the authenticity of incoming payment webhook notifications, as the signing key used to validate their signature is empty by default, allowing unauthenticated attackers to forge a valid signature and mark arbitrary WooCommerce orders as paid without payment.
A vulnerability exists in the Super Payments WordPress plugin in versions prior to 1.43.1, where the plugin fails to properly authenticate incoming payment webhook notifications. The signing key used for signature validation is empty by default, allowing unauthenticated attackers to forge valid signatures and falsely mark WooCommerce orders as paid without actual payment.
Users are advised to update the Super Payments WordPress plugin to version 1.43.1 or later.
