Serial Codes Generator and Validator with WooCommerce Support < 2.7.8 - Cross-Site Request Forgery via [placeholder]

Description

The Serial Codes Generator and Validator with WooCommerce Support plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.7.7. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action granted they can trick a site administrator into performing an action such as clicking on a link.
