Authorization Bypass in OpenClaw via Surviving Device Session

Compliance Impact

The vulnerability allows unauthorized access to persist longer than intended by bypassing revocation controls, which weakens authorization mechanisms.

Such unauthorized prolonged access could potentially lead to violations of compliance requirements related to data confidentiality, integrity, and access control as mandated by standards like GDPR and HIPAA.

However, the provided information does not explicitly state the direct impact on compliance with these regulations.

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 It allows a paired device with an active session to regain node token authority even after that authority has been revoked.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If a node token was revoked on an older version, it is recommended to restart the gateway and re-pair the affected device to remove any stale sessions.

Detection Guidance

There is no specific detection method or commands provided in the available resources to identify this vulnerability on your network or system.

However, since the vulnerability involves a surviving pairing-scoped device session re-establishing node token authority after revocation, monitoring for unexpected WebSocket node-level access from paired devices after token revocation could be an indicator.

To mitigate, it is recommended to upgrade OpenClaw to version 2026.5.26 or later and, if a node token was revoked on an older version, restart the gateway and re-pair the affected device to remove stale sessions.
