Summary

The Airwallex Online Payments Gateway WordPress plugin before 1.36.0 does not verify that an incoming payment notification genuinely comes from the payment provider when no webhook secret has been configured, allowing unauthenticated attackers to forge one and mark orders as paid without paying.

Risk Assessment

Attackers can mark orders as paid without actual payment, leading to financial loss. This requires no webhook secret to be configured.

Recommendation

Update the Airwallex Online Payments Gateway plugin to version 1.36.0 or later. Configure a webhook secret to verify notification authenticity.
