What the vulnerability does
The Contact Form 7 Redirect & Thank You Page plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'post' parameter in all versions up to, and including, 1.0.7 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.

This can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim.
What an attacker can do
Inject and execute malicious JavaScript in a user's browser when they visit a crafted page or link.
Potential impact on your site
Administrators and users visiting malicious links could have their sessions hijacked, credentials stolen, or be tricked into performing unwanted actions on the site.
Conditions required to exploit
