# WWBN AVideo: redirect flaw lets uploaders make server send internal requests

WWBN AVideo before 29.4.0 fetches a stored video link to read its content type and follows redirects without rechecking the destination against its SSRF filter. An authenticated uploader can point a video link at a redirector, so the server sends GET requests to internal addresses when visitors view the video, enabling internal port scanning.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed AVideo version in the project's version file or admin panel; versions below `29.4.0` are affected
- Review whether untrusted users can upload or edit videos with external video links

## Fix

- Upgrade AVideo to `29.4.0` or later
- Until upgraded, restrict who can upload videos or set external video links

## From the sources

WWBN AVideo before 29.4.0 contains a blind server-side request forgery vulnerability in getHeaderContentTypeFromURL() because get_headers() follows redirects without re-validating targets with isSSRFSafeURL(). Authenticated uploaders can store a videoLink pointing to a redirector, causing internal GET requests when visitors view the video, enabling internal port scanning via the embed-versus-video render oracle.
