Cross-site scripting error

Hello,
I found an error XSS in file getresponse-integration\gr-templates\admin\settings\functions.php line 98.
From:
<?php gr_return_campaign_selector(
‘checkout_campaign’,
gr_get_value( ‘checkout_campaign’ ),
gr_get_option( ‘checkout_campaign_autoresponder_status’ ),
gr_get_option( ‘checkout_campaign_autoresponder’ ),
! $checkout_checked
); ?>
