    Title
    MC4WP: Mailchimp for WordPress < 4.15.0 - Unauthenticated Arbitrary Shortcode Execution via Dynamic Content Tag
    Summary
    The MC4WP: Mailchimp for WordPress WordPress plugin before 4.15.0 does not prevent request-derived values in its dynamic content tags from being processed as shortcodes when a form is embedded with its block, allowing unauthenticated visitors to execute arbitrary registered shortcodes with attacker-chosen attributes. This requires the site owner to have added a request-derived tag to the form content and to embed the form with the block rather than the classic shortcode.
    Severity
    4.8 (Medium)
