Overview

open-webui is an Open WebUI

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) through get_content_from_url in retrieval/utils.py, SafeWebBaseLoader in web/base.py, and image_edits in routers/images.py. An attacker can cause the server to fetch internal services or cloud metadata by providing a public URL that returns a 3xx redirect to a private address. The redirected response is then returned to the attacker, exposing internal resources such as RFC1918 hosts, loopback services, and 169.254.169.254 metadata endpoints.
