PodcastGenerator 3.2.9 contains a blind server-side request forgery vulnerability that allows attackers to inject XML in the episode upload form. Attackers can manipulate the shortdesc parameter to trigger external HTTP requests to arbitrary endpoints during podcast episode creation.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
