Podlove Podcast Publisher < 4.0.12 - Authenticated (Contributor+) Server-Side Request Forgery

Description

The Podlove Podcast Publisher plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.0.11 via the fetch_url_meta function. This makes it possible for authenticated attackers, with contributor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
