DescriptionCVE.org

OpenClaw before 2026.3.22 contains a privilege escalation vulnerability in the device.pair.approve method that allows an operator.pairing approver to approve pending device requests with broader operator scopes than the approver actually holds. Attackers can exploit insufficient scope validation to escalate privileges to operator.admin and achieve remote code execution on the Node infrastructure.

AnalysisAI

Privilege escalation in OpenClaw before 2026.3.22 enables authenticated attackers with operator.pairing approver role to escalate privileges to operator.admin through insufficient scope validation in the device.pair.approve method. Exploitation allows approval of device requests with broader operator scopes than the approver legitimately holds, ultimately enabling remote code execution on Node infrastructure. Affects OpenClaw deployments where role-based access control enforces operator privilege hierarchies. No public exploit identified at time of analysis.

Technical ContextAI

CWE-648 scope validation failure permits horizontal privilege escalation through device pairing workflow. The device.pair.approve method fails to verify that requested operator scopes remain within the approver's granted scope boundaries, allowing lateral movement from operator.pairing to operator.admin. Exploitation chain terminates in RCE against Node.js runtime infrastructure.

RemediationAI

Vendor-released patch: upgrade to OpenClaw version 2026.3.22 or later, which implements proper scope validation in device pairing approval workflows. Upstream fixes available via GitHub commits 630f1479c44f78484dfa21bb407cbe6f171dac87 and fc2d29ea926f47c428c556e92ec981441228d2a4. Temporary mitigation: restrict operator.pairing approver role assignments to only operators who already hold operator.admin privileges, effectively neutralizing the escalation path until patching. Review audit logs for suspicious device pairing approvals where granted scopes exceed approver permissions. Advisory: https://github.com/openclaw/openclaw/security/advisories/GHSA-hf68-49fm-59cq
