Short explanation
WWBN AVideo before versions 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.
This vulnerability allows an authenticated uploader to issue requests to internal network resources and perform internal port scanning via the embed-versus-video render oracle.
What should be done?
- Upgrade AVideo to version 29.4.0 or later
- Apply the provided patch commit references
- Follow vendor advisory guidance
