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.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
