Problem Description

Allowing user-defined webhooks introduces a security vulnerability. This occurs because webhook requests are initiated directly from the server hosting the open-webui backend.

Impact:

  • Leakage of the backend server's IP address.
  • Increased risk of information disclosure and targeted attacks against the server infrastructure.

Desired Solution you'd like

Having a switch inside the admin panel, or a environment variable that will block the sending of webhooks

Or at least only allow well known webhooks urls

Alternatives Considered
