Overview

open-webui is an Open WebUI

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the fetch process when HTTP redirects are followed and the destination of the redirect is not validated against excluded hosts or private/internal address checks. An attacker can access internal or excluded network resources by submitting a URL that causes the server to follow a redirect to a restricted address. This is only exploitable if the AIOHTTP_CLIENT_ALLOW_REDIRECTS setting is enabled.
