Issues and Series for Newspapers, Magazines, Publishers, Writers < 3.1.4 - Cross-Site Request Forgery

Description

The Issues and Series for Newspapers, Magazines, Publishers, Writers plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.3. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
