Upgrade open-webui to version 0.11.0 or higher.
Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) through the process of hostname resolution and subsequent HTTP connection. An attacker can access internal network resources and sensitive metadata by submitting a specially crafted URL and controlling the authoritative DNS server to alternate responses between the initial validation and the actual connection. This may result in the server disclosing internal information, including cloud instance credentials or OAuth tokens, to the attacker. This is only exploitable if the attacker has an account on the instance and controls the authoritative DNS for a submitted hostname, and, for the OAuth path, if OAuth login is configured with a user-influenced picture claim.
