Pass data (url, ref url, cookie data) to hidden fields

Hello,

I was wondering if there is a way to capture these types of data with hidden fields:

1. landing page url
2. referral url
3. cookie data
   The reason to use hidden fields for this is to make data available for passing to Oracle Eloqua.

Can this be done via unbounce directly or via Google Tag Manager?

Thanks
PS: To be clear I’m NOT referring to passing data via UTM or any url parameter
