CVE-2026-32057: Openclaw Auth Bypass Vulnerability

CVE-2026-32057 Overview

CVE-2026-32057 is an authentication bypass vulnerability affecting OpenClaw versions prior to 2026.2.25. The vulnerability exists in the trusted-proxy Control UI pairing mechanism, which accepts client.id=control-ui without proper device identity verification. An authenticated user with a node role websocket client can exploit this flaw by using the control-ui client identifier to skip pairing requirements and gain unauthorized access to node event execution flows.

Critical Impact

Attackers with low-privilege node role access can bypass authentication controls to gain unauthorized access to node event execution flows, potentially compromising system integrity.

Affected Products

• OpenClaw versions prior to 2026.2.25
• OpenClaw for Node.js environments

Technical Details for CVE-2026-32057

Vulnerability Analysis

This authentication bypass vulnerability (CWE-807: Reliance on Untrusted Inputs in a Security Decision) stems from improper validation in the WebSocket connection message handler. The trusted-proxy authentication mechanism fails to verify that clients claiming the control-ui identity actually possess the required operator role privileges. This design flaw allows authenticated users with lower-privilege node roles to impersonate control-ui clients and bypass the normal pairing verification process.

The vulnerability is exploitable over the network by users who already have authenticated websocket access with a node role. While the attacker requires some level of authentication (low privileges required), no user interaction is needed to exploit the vulnerability. Successful exploitation primarily affects integrity, allowing unauthorized modifications to node event execution flows.

Root Cause

The root cause lies in the WebSocket message handler's trusted-proxy authentication logic within src/gateway/server/ws-connection/message-handler.ts. The original implementation checked if a client identified as control-ui and verified the authentication mode and method, but failed to validate that the requesting client actually possessed the operator role. This oversight allowed any authenticated client to claim the control-ui identity and bypass pairing requirements intended for legitimate control UI operators.

Attack Vector

An attacker exploits this vulnerability by establishing an authenticated WebSocket connection with a node role, then sending requests with client.id=control-ui. Because the server only verified the client identifier and trusted-proxy authentication mode without checking role authorization, the attacker could bypass the pairing mechanism designed to restrict control-ui access. This grants unauthorized access to node event execution functionality that should be restricted to operators.

           }
           const trustedProxyAuthOk =
             isControlUi &&
+            role === "operator" &&
             resolvedAuth.mode === "trusted-proxy" &&
             authOk &&
             authMethod === "trusted-proxy";

The patch adds a critical role verification check (role === "operator") ensuring that only clients with the appropriate operator role can successfully authenticate through the trusted-proxy control-ui mechanism.

Detection Methods for CVE-2026-32057

Indicators of Compromise

• WebSocket connections using client.id=control-ui from clients that do not have the operator role
• Unexpected node event execution requests originating from non-operator authenticated sessions
• Anomalous pairing bypass attempts in gateway server logs

Detection Strategies

• Monitor WebSocket authentication logs for connections claiming control-ui identity with non-operator roles
• Implement alerts for trusted-proxy authentication attempts that lack proper role authorization
• Review gateway server logs for repeated authentication bypass patterns targeting the control-ui mechanism

Monitoring Recommendations

• Enable detailed logging for all WebSocket message handler authentication events
• Set up alerting for any control-ui client.id usage from non-operator role sessions
• Audit node event execution flows for unauthorized access patterns

How to Mitigate CVE-2026-32057

Immediate Actions Required

• Upgrade OpenClaw to version 2026.2.25 or later immediately
• Review logs for any historical exploitation attempts using the control-ui client identifier bypass
• Audit all existing node role accounts for suspicious activity

Patch Information

The vulnerability has been addressed in OpenClaw version 2026.2.25. The fix implements proper role verification in the trusted-proxy authentication mechanism, ensuring that only clients with the operator role can authenticate as control-ui. The security patch is available via the GitHub Commit. Additional details are available in the GitHub Security Advisory.

Workarounds

• Restrict network access to the OpenClaw gateway server to trusted networks only until patching is complete
• Implement additional network-level controls to limit WebSocket connections to verified operator workstations
• Monitor and audit all control-ui authentication attempts pending the upgrade

# Configuration example - Verify OpenClaw version
openclaw --version
# Ensure version is 2026.2.25 or later

# Review authentication logs for suspicious activity
grep "client.id=control-ui" /var/log/openclaw/gateway.log
