CVE-2026-114634

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.
