XSS vulnerability

Greetings,
My host told me that my site scan discovered XSS vulnerability within the Easy Blog Login in.

I don't really need that functionality, I compose all my posts on the backend and don't need to login on the front end.

Can I remove the login capability from within Easy Blog pages? The "lock" icon is what I am referring to.

Or . . . is there anything else I can do to remove the threat?

Thanks.
