What fixes it
- 1.43.1Super PaymentsCVE List
A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.
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.
