Description

The MailChimp Subscribe Forms plugin for WordPress is vulnerable to Open Redirect in versions up to, and including, 4.0.9.3. This is due to the application failing to properly verify a user-supplied input parameter. This makes it possible for unauthenticated attackers to exploit this issue and redirect users to arbitrary web sites and conduct phishing attacks; other attacks are also possible.
