Authorization Bypass in OpenClaw via Surviving Device Session

Publication date: 2026-06-16

Last updated on: 2026-06-16

Assigner: VulnCheck

Description
OpenClaw before 2026.5.26 contains an authorization bypass vulnerability where a surviving pairing-scoped device session can re-establish node token authority after revocation. Attackers with a paired device can regain WebSocket node-level access without renewed approval, weakening revocation controls and maintaining unauthorized access longer than intended.

Executive Summary

CVE-2026-53843 is an authorization bypass vulnerability in OpenClaw versions prior to 2026.5.26. It allows a paired device with an active session to regain node token authority even after that authority has been revoked. This means that an attacker who has access to a paired device can re-establish WebSocket node-level access without needing renewed user approval.

The vulnerability occurs because a surviving pairing-scoped device session can bypass revocation controls, enabling unauthorized access to persist longer than intended.

Impact Analysis

This vulnerability can have serious impacts on the confidentiality, integrity, and availability of your system. Attackers with access to a paired device can regain unauthorized WebSocket node-level access without renewed approval, effectively bypassing revocation controls.

This unauthorized access can persist longer than intended, potentially allowing attackers to maintain control or access sensitive data, disrupt services, or manipulate system operations.

Mitigation Strategies

To mitigate the CVE-2026-53843 vulnerability, you should upgrade OpenClaw to version 2026.5.26 or later.

If a node token was revoked on an older version, it is recommended to restart the gateway and re-pair the affected device to remove any stale sessions.
