Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) through the OAuthManager profile picture fetch path in the OAuth handling code. An attacker can make the server send outbound requests to arbitrary URLs by supplying a malicious OAuth profile picture URL during authentication. This lets the attacker probe internal services or metadata endpoints from the Open WebUI host and can expose internal network data or trigger requests against protected infrastructure.
