The Podlove Podcast Publisher plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.2.2. This is due to missing or incorrect nonce validation on the ajaxtranscriptdelete() function. This makes it possible for unauthenticated attackers to delete arbitrary episode transcripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
