Short explanation

A vulnerability in the CryptoCloud WordPress plugin from version 3.0.0 through 3.0.1 causes integrity checks for payment notifications to be skipped while the webhook secret remains at its empty default [S0]. Unauthenticated attackers can mark arbitrary orders as paid or failed without any payment being made [S0].

Why does it matter?

This vulnerability allows unauthenticated attackers to manipulate payment gateway callbacks and alter order statuses without authorization, impacting transaction integrity [S0].

What should be done?

  • Monitor vendor advisories and updates as patch status is currently unknown [S0]
  • Configure a non-empty webhook secret instead of leaving it at the default [S0]
  • Review plugin configurations and payment gateway callbacks [S0]

Show the technical text from the sources

The CryptoCloud WordPress plugin from 3.0.0 through 3.0.1 does not verify the authenticity of the payment notifications received by its gateway callback, as the integrity check is skipped while the webhook secret is left at its empty default, allowing unauthenticated attackers to mark arbitrary orders as paid or failed without any payment being made.
