7th percentile - higher than 7% of all known CVEs

Summary

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

Risk Assessment

An attacker can mark any order as paid without making a payment, causing financial losses. The risk affects WooCommerce stores using this plugin.

Recommendation

Update the plugin to a version later than 1.2.10 and configure a non-empty validation secret. Review order history for forged confirmations.
