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) via the renderVegaVisualization process. An attacker can cause a victim's browser to make arbitrary outbound GET requests and read responses from same-origin or CORS-permissive targets by embedding specially crafted Vega or Vega-Lite chart specifications in chat content. This is only exploitable if a user with sufficient privileges can place such content where another user will view it, and the victim opens the message.
