CVE-2024-8680: MailChimp for Wordpress <= 4.9.16 - Authenticated (Administrator+) Stored Cross-Site Scripting
First published: Sat Sep 21 2024(Updated: )
The MC4WP: Mailchimp for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.9.16 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
