OpenClaw < 2026.5.18 - Exec Lifecycle Event Forgery via Paired Node

Published Jun 11, 2026 CVSS 4.0 · 8.6 High EPSS < 1% KEV · Not listed
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.
