Create a Custom HTML field then enable content plugins under its parameters. Now you can use CBSubs substitutions like the following.
Code:
[cbsubs:if user="#displayed" plan="PLAN_ID" status="A"]
Plan Name: [cbsubs:plans user="#displayed" plan="PLAN_ID" output="name" /]
Subscription Date: [cbsubs:subscriptions user="#displayed" plan="PLAN_ID" output="signup_date" /]
Expiration Date: [cbsubs:subscriptions user="#displayed" plan="PLAN_ID" output="expiry_date" /]
[/cbsubs:if]
Replace PLAN_ID with the id of the plan you want to check the subscription status of. Review the cbsubsbot description in System > Plugins for further CBSubs substitution usage information. The cbsubs:if prevents it from displaying anything unless the subscription is in an active status, but you can remove that if you like.
