CVE-2024-8850: MC4WP: Mailchimp for WordPress 4.9.9 - 4.9.16 - Reflected Cross-Site Scripting
First published: Thu Sep 19 2024(Updated: )
The MC4WP: Mailchimp for WordPress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'email' parameter when a placeholder such as {email} is used for the field in versions 4.9.9 to 4.9.16 due to insufficient input sanitization and output escaping. 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.
