Name of the Vulnerable Software and Affected Versions: MailChimp Forms by MailMunch plugin for WordPress versions up to, and including, 3.2.3

Description: The MailChimp Forms by MailMunch plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add query arg without appropriate escaping on the URL. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Recommendations: For versions up to, and including, 3.2.3, update to a version higher than 3.2.3 to resolve the issue. As a temporary workaround, consider restricting access to the plugin's functionality until a patch is available.
