CVE-2026-53816

Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um Sicherheitsmechanismen zu umgehen, erhöhte Berechtigungen zu erlangen, Informationen offenzulegen, Konfigurationen zu manipulieren, beliebige Befehle oder Code auszuführen sowie interne Systeme über SSRF anzugreifen.

### Summary OpenClaw nodes send lifecycle events back to the gateway. In affected releases, a paired node could send an exec lifecycle event that was accepted without enough provenance tying it to an authorized `system.run` request. This issue affects the node event boundary. It does not allow an unauthenticated caller to reach the gateway; the attacker must already control a paired node connection. ### Affected configurations This affects deployments with a paired node where that node can send crafted `node.event` messages to the gateway and the target agent/session can process exec lifecycle events. ### Impact A malicious or compromised paired node could make the gateway treat attacker-supplied event data as an exec lifecycle result. In the vulnerable flow, that could steer the target session into an exec-event path that exposed capabilities the reduced node surface should not have provided. The issue is a missing provenance check for node-originated lifecycle events. ### Patched Versions The first stable patched version is `2026.5.18`. ### Mitigations Upgrade to `openclaw@2026.5.18` or later. Pair nodes only from trusted environments, and remove/re-pair nodes that may have been compromised.
