CVE-2026-53816
OpenClaw < 2026.5.18 - Exec Lifecycle Event Forgery via Paired Node
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.
