## Technical details

A server-side request forgery (SSRF) vulnerability exists in the canvas.present capability where URL risk evaluation enforced by canvas.navigate is bypassed. Attackers with gateway or agent access can use canvas.present to make the node's WebView send requests to localhost, private networks, or tailnet services from the user's machine. The vulnerability requires authenticated access to the OpenClaw gateway or agent.
