Smart App Banner <= 1.1.2 - Cross-Site Request Forgery via wsl_smart_app_banner_options

The Smart App Banner plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1.2. This is due to missing or incorrect nonce validation on the wsl_smart_app_banner_options function. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
