Summary

The Customer Engagement System WordPress plugin before 2.0.2 does not restrict access to its MailChimp interest-group lookup or validate the API key supplied to it, which enables server-side request forgery (CWE-918). An unauthenticated attacker can make the server open connections to arbitrary internal hosts and ports and infer from response timing which ones are reachable. A public exploit is linked in the references.
