Simple Testimonials Showcase <= 1.1.5 - Cross-Site Request Forgery

Description The Simple Testimonials Showcase plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1.5. This is due to missing or incorrect nonce validation on the sts_save_settings() function. This makes it possible for unauthenticated attackers to update 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.
