Podlove Podcast Publisher <= 4.1.13 - Cross-Site Request Forgery to Remote Code Execution

The Podlove Podcast Publisher plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.1.13. This is due to missing or incorrect nonce validation on the 'get', 'update', 'create', and 'delete' functions. This makes it possible for unauthenticated attackers to modify templates and achieve remote code execution via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
