The Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Credit Card field's 'Card Type' sub-field (input_.4) in all versions up to, and including, 2.9.30. This is due to the get_value_entry_detail() method in the GF_Field_CreditCard class outputting the card type value without escaping, combined with get_value_save_entry() accepting and storing unsanitized user input for the input_.4 parameter. The Card Type field is not rendered on the frontend form (it is normally derived from the card number), but the backend submission parser blindly accepts it if included in the POST request. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the form entry in the WordPress dashboard.
