High (8.6) in openclaw openclaw. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in openclaw 2026.5.18.
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.
