What the vulnerability does

01Description

The Tectite Forms plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3. This is due to missing or incorrect nonce validation on the admin_init function. This makes it possible for unauthenticated attackers to modify the plugin's settings, including the tectite_forms_button option, via a forged request via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
