Vulnerability Title
OpenClaw < 2026.5.18 - Exec Lifecycle Event Forgery via Paired Node
Source: CVE Program / CVE List V5
Vulnerability 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.
