Input validation vulnerability in Contact Form 7 – Dynamic Text Extension 2.0.3

The Contact Form 7 Dynamic Text Extension plugin for WordPress is not secure in versions before 2.0.3. Attackers can inject malicious code to web pages if they can convince a user to take an action, like clicking a link. This malicious code would then be executed, allowing the attacker to gain access to the website. To prevent this, make sure that you are using version 2.0.3 or higher.
