Leadster <= 1.1.2 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Leadster plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1.2. This is due to missing nonce validation on the leadster_script_code_action() function hooked via 'admin_post'. This makes it possible for unauthenticated attackers to update the plugin's script code via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
