Received Received - Intake
Insufficient Provenance Validation in OpenClaw Node Event Handling

Publication date: 2026-06-11

Last updated on: 2026-06-11

Assigner: VulnCheck

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.

Executive Summary

This vulnerability exists in OpenClaw versions before 2026.5.18 and involves insufficient provenance validation in node event handling.

Specifically, paired nodes can forge exec lifecycle events without requiring system.run authorization.

A malicious or compromised paired node can send crafted node.event messages to the gateway, which can steer target sessions into exec-event paths that expose capabilities that should not be available given the reduced node surface.

Impact Analysis

This vulnerability can allow a malicious or compromised paired node to execute unauthorized lifecycle events on target sessions.

As a result, it exposes capabilities that are supposed to be restricted, potentially leading to unauthorized actions or access within the system.
