Authenticated internal-response disclosure via OAuth redirects
Published Jun 23, 2026 · Updated Jun 23, 2026
Server-side request forgery in Open WebUI before 0.9.6 allows remote authenticated users to read internal responses through OAuth images. OAuth _process_picture_url validates only the initial picture URL, follows redirects by default, then stores the fetched body in profile_image_url. Exploitation requires a valid configured OAuth identity and picture syncing or OAuth signup, and exposes data reachable from the server.
