we should not store credit card info so please add these lines:

```php
<?php
unset($paymentDetails['CARDCODE']);
unset($paymentDetails['CARDCVV']);
unset($paymentDetails['CARDFULLNAME']);
unset($paymentDetails['CARDVALIDITYDATE']);

$order->getPayment()->setDetails((array) $this->sanitizePayment($paymentDetails));
```

and same lines to catch block. 

P.S. I've introduces `SensitiveValue` object in 0.7 version so when we switch to it we can remove these unset statements.
