Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

PodcastGenerator 3.2.9 contains a blind server-side request forgery (SSRF) vulnerability in the episode upload form. Attackers can manipulate the 'shortdesc' parameter to inject XML and cause the server to make HTTP requests to arbitrary internal or external endpoints. This critical flaw (CVSS 9.8) enables internal service enumeration, cloud metadata access, and potential pivot attacks.

MitigationUpgrade to a patched version of PodcastGenerator; if unavailable, implement strict input validation on the 'shortdesc' parameter to reject XML payloads and deploy network-level controls to restrict outbound requests from the application server.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify PodcastGenerator version
    Locate the version file or admin dashboard version display in the PodcastGenerator installation directory (commonly version.php, or check the admin interface footer/summary page)
    Affected if The installed version is exactly 3.2.9
  2. Verify episode upload functionality exists
    Access the admin panel and navigate to the episode upload form (typically under 'Episodes' or 'Add Episode' in the web interface)
    Affected if The episode upload form is accessible and functional in the running application
  3. Confirm 'shortdesc' field accepts input
    Load the episode upload form in a browser or via API request and inspect the HTML form fields to locate the 'shortdesc' parameter
    Affected if The 'shortdesc' text field is present and accepts user input without server-side validation rejection

You are affected if running PodcastGenerator version 3.2.9 and the episode upload form with the 'shortdesc' field is accessible and functional.
