Advisory
Source description from Wordfence Intelligence, credited to William Bastos.
The Contact Form 7 plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 5.9.4. This is due to insufficient validation on the redirect url supplied via accessing the contact form with a spoofed page. This makes it possible for unauthenticated attackers to redirect site users to potentially malicious sites if they can successfully trick them into performing an action.
