Super Payments
Monthly
Forging payment webhook signatures in the Super Payments WordPress plugin (before 1.43.1) allows unauthenticated remote attackers to mark arbitrary WooCommerce orders as paid without payment, because the plugin ships with an empty signature-validation signing key by default. The medium-severity (CVSS 5.3) integrity flaw has business impact that exceeds its raw score; publicly available exploit code exists, though no confirmed active exploitation has been observed (not listed in CISA KEV). Affected sites are those using the vulnerable plugin with WooCommerce and exposed webhook endpoints, and the default configuration itself is the enabling condition.
