NVD description
OpenClaw before 2026.5.18 contains an insufficient provenance validation vulnerability in node event handling that allows paired nodes to forge exec lifecycle events without system.run authorization. A malicious or compromised paired node can send crafted node.event messages to the gateway, steering target sessions into exec-event paths that expose capabilities the reduced node surface should not provide.
What to do
- Upgrade OpenClaw to
2026.5.18or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
