Benchmark Email Lite < 4.2 - Cross-Site Request Forgery via page_settings()

Description The Benchmark Email Lite plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.1. This is due to missing or incorrect nonce validation on the page_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.
