What fixes it

  • 1.36.0Airwallex Online Payments GatewayCVE 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 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.
