The advisory

The Payment Forms for Paystack WordPress plugin before 4.0.6 does not properly restrict access to a page that displays its stored configuration, allowing users with the Contributor role and above to view secret payment-gateway API credentials, both the live and test secret keys, which grant full access to the site owner's payment account.
