CVE-2026-101883
OpenClaw Windows Node through 2026.9.4 contains a server-side request forgery vulnerability in the canvas.present capability that bypasses URL risk evaluation enforced by canvas.navigate.
Does this matter?
Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.
Description
OpenClaw Windows Node through 2026.9.4 contains a server-side request forgery vulnerability in the canvas.present capability that bypasses URL risk evaluation enforced by canvas.navigate. Attackers with gateway or agent access can issue canvas.present to make the node's WebView send requests to localhost, private networks, or tailnet services from the user's machine.
