Payex Payment Gateway for WooCommerce <= 1.2.10 - Unauthenticated Payment Confirmation Forgery via Empty-Default Secret Key

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The Payex Payment Gateway for Woocommerce WordPress plugin through 1.2.10 does not properly verify the authenticity of incoming payment notifications, relying on a validation secret that is empty by default, allowing unauthenticated attackers to forge a valid payment confirmation and mark any order as paid.
