WP Google Review Slider < 16.1 - Cross-Site Request Forgery to SQL Injection

Description

The WP Google Review Slider plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 16.0. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to inject SQL queries via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
