DescriptionCVE.org

OpenClaw before 2026.3.28 contains a privilege escalation vulnerability in the /pair approve command path that fails to forward caller scopes into the core approval check. A caller with pairing privileges but without admin privileges can approve pending device requests asking for broader scopes including admin access by exploiting the missing scope validation in extensions/device-pair/index.ts and src/infra/device-pairing.ts.

AnalysisAI

Privilege escalation in OpenClaw (pre-2026.3.28) allows unauthenticated remote attackers to gain administrative access by exploiting missing scope validation in the device pairing approval workflow. The /pair approve command fails to forward caller scopes during approval checks, enabling attackers with basic pairing privileges-or potentially no privileges given the CVSS PR:N vector-to approve device requests with elevated admin scopes. EPSS data not available; no public exploit identified at time of analysis, though the CVSS 9.8 reflects trivial exploitation due to network accessibility, low complexity, and no authentication barrier. Vendor-released patch: commit e403dec (2026.3.28+).

Technical ContextAI

OpenClaw implements a device pairing system where devices request access with specific permission scopes (including admin-level access). The vulnerability resides in extensions/device-pair/index.ts and src/infra/device-pairing.ts, where the /pair approve command path processes approval requests. The code fails to propagate the caller's permission scopes into the core approval validation logic (CWE-863: Incorrect Authorization). This allows the approval function to proceed without verifying whether the caller has sufficient privileges to grant the requested scopes. Essentially, the system checks if a pairing request exists but not whether the approving party is authorized to grant admin-level permissions. The affected product per CPE is cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:*:*:*, indicating all versions prior to the March 2026 patch.

RemediationAI

Upgrade immediately to OpenClaw version 2026.3.28 or later, which includes the fix committed in e403decb6e20091b5402780a7ccd2085f98aa3cd. The patch implements proper scope validation by forwarding caller permission scopes into the approval authorization check, ensuring users cannot approve requests for scopes exceeding their own privileges. Organizations unable to upgrade immediately should disable the /pair approve endpoint or restrict network access to the device pairing API to trusted administrators only until patching is complete. Review audit logs for unauthorized device approvals or privilege escalations that occurred before remediation.
