Link Injection

I am requesting support regarding the implementation of the Marketo forms at our WordPress website. On the following pages:
The user can do Link Injection. This results in a unsafe way of working. Please let me know how we can proceed in preventing this from happening. We use the code from the Marketo website 1 on 1 as suggested in the backend. 
I hope you can help me as soon as possible,
