Name of the Vulnerable Software and Affected Versions: MC4WP: Mailchimp for WordPress plugin for WordPress versions 4.9.9 through 4.9.16

Description: The issue is related to Reflected Cross-Site Scripting via the email parameter when a placeholder such as {email} is used for the field. This is due to insufficient input sanitization and output escaping, making 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 4.9.9 through 4.9.16, consider disabling the use of the email parameter with placeholders until a patch is available. Restrict access to pages that use the email parameter to minimize the risk of exploitation. Avoid using the email parameter in affected fields until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
