CVE-2026-62219: Openclaw Authorization Bypass Vulnerability

CVE-2026-62219 Overview

CVE-2026-62219 is an authorization bypass vulnerability in OpenClaw, a Node.js-based application. The flaw resides in the hooks allowedAgentIds validation logic. A lower-trust caller or configured input path can submit blank agent IDs to bypass agent ID restrictions. This grants access to actions that should require stronger authorization or policy checks. The issue is tracked under CWE-863: Incorrect Authorization and affects OpenClaw versions 2026.2.12 through versions before 2026.5.26.

Critical Impact
Attackers with low-level access can bypass agent ID authorization checks by submitting blank agent IDs, gaining the ability to perform privileged actions restricted by policy.

Affected Products

OpenClaw 2026.2.12 and later releases before 2026.5.26
OpenClaw deployments running on Node.js runtime
Any application depending on the openclaw package for agent authorization

Technical Details for CVE-2026-62219

Vulnerability Analysis

The vulnerability is an authorization bypass in the hooks subsystem of OpenClaw. The allowedAgentIds validation is intended to restrict actions to callers whose agent identifiers match an approved allowlist. The validation logic does not correctly handle empty or blank agent ID values. When a caller submits a blank agent ID, the check treats the input as passing rather than rejecting it. This allows a lower-trust caller to invoke actions gated behind stronger authorization or policy enforcement.

The vulnerability is network-exploitable and requires low privileges. There is no user interaction requirement, and the attack complexity is low. Integrity impact is high because attackers can perform actions that alter application state. Confidentiality impact is limited to information exposed through the bypassed actions.

Root Cause

The root cause is improper validation of the agent identifier input in the hooks authorization flow. The code path fails to treat blank or empty strings as invalid before comparing against the allowedAgentIds allowlist. This is a classic incorrect authorization pattern classified as CWE-863. Missing input normalization and missing default-deny behavior on empty inputs form the core defect.

Attack Vector

An attacker sends a request to the vulnerable OpenClaw endpoint with the agent ID field set to a blank value. The hooks validation accepts the blank input as satisfying the allowlist check. The attacker then invokes actions that should be restricted to authorized agent identifiers. Exploitation does not require prior compromise of a privileged account, only the ability to reach the network endpoint and hold low-level authentication.

No verified public exploit code examples are available. Refer to the VulnCheck Advisory on OpenClaw and the GitHub Security Advisory GHSA-724r-v4wf-mqc5 for further technical details.

Detection Methods for CVE-2026-62219

Indicators of Compromise

Requests to OpenClaw hook endpoints containing empty or whitespace-only values in the agent ID field
Successful invocation of privileged hook actions by callers whose agent IDs do not appear in the allowedAgentIds allowlist
Anomalous action execution originating from lower-trust service accounts or API tokens

Detection Strategies

Inspect application and reverse proxy logs for OpenClaw hook requests with blank, null, or whitespace agent ID parameters
Correlate authorization decisions against caller identity to flag actions executed without a matching allowlisted agent ID
Deploy runtime application self-protection or WAF rules that reject requests to hook endpoints when the agent ID field is empty

Monitoring Recommendations

Enable verbose logging on OpenClaw hook authorization decisions and forward events to a centralized SIEM
Alert on privilege-relevant hook actions performed by service identities that historically do not invoke them
Baseline normal agent ID values seen in production traffic and alert on deviations, including empty submissions

How to Mitigate CVE-2026-62219

Immediate Actions Required

Upgrade OpenClaw to version 2026.5.26 or later on all affected Node.js deployments
Audit hook endpoint logs for prior requests submitted with blank agent IDs to identify possible exploitation
Restrict network exposure of OpenClaw hook endpoints to trusted callers using network segmentation or authenticated reverse proxies

Patch Information

OpenClaw addressed the authorization bypass in version 2026.5.26. Consult the GitHub Security Advisory GHSA-724r-v4wf-mqc5 for the fixed release and the VulnCheck Advisory for additional remediation context. Update the openclaw dependency in package.json and rebuild affected services.

Workarounds

Add an input validation layer in front of OpenClaw hooks that rejects requests where the agent ID field is empty, null, or whitespace
Enforce default-deny authorization for hook actions when the agent ID cannot be resolved to an entry in allowedAgentIds
Apply upstream WAF or API gateway rules that require a non-empty agent ID pattern before forwarding traffic to OpenClaw

bash

# Update OpenClaw to the patched release
npm install openclaw@2026.5.26

# Verify installed version
npm ls openclaw
