Authorization Bypass in OpenClaw Model Override

Executive Summary

CVE-2026-62186 is an authorization bypass vulnerability in OpenClaw versions before 2026.6.8. The flaw exists in the OpenAI-compatible HTTP model overrides feature, where lower-trust callers or misconfigured input paths can perform actions that require stronger authorization checks.

Attackers can exploit this vulnerability by bypassing admin authorization policies, allowing them to execute restricted operations. The issue is classified under CWE-862 (Missing Authorization) and CWE-863 (Incorrect Authorization), indicating that the software fails to properly enforce access controls.

This vulnerability does not affect OpenClaw's trusted-operator model. It has a high severity rating with a CVSS v3.1 score of 7.6 and a CVSS v4.0 score of 7.2.

Detection Guidance

Detecting this vulnerability requires checking for the presence of vulnerable OpenClaw versions and monitoring for suspicious activity related to OpenAI-compatible HTTP model overrides.

• Verify the installed OpenClaw version. If it is before 2026.6.8, the system is vulnerable. You can check the version using the OpenClaw CLI or by inspecting the package metadata.
• Monitor network traffic for unusual HTTP requests targeting OpenClaw endpoints, particularly those involving model override parameters. Look for requests that attempt to bypass authorization checks.
• Review OpenClaw logs for unauthorized access attempts or actions performed by lower-trust callers. Focus on logs related to the OpenAI-compatible HTTP model override feature.
• Use vulnerability scanning tools to detect the presence of CVE-2026-62186. Tools like Nessus, OpenVAS, or custom scripts can help identify vulnerable installations.

Impact Analysis

If you are using an affected version of OpenClaw (before 2026.6.8), this vulnerability could allow attackers with lower trust levels to bypass authorization policies and perform unauthorized actions.

• Unauthorized execution of restricted operations, potentially leading to data manipulation or access to sensitive functions.
• Increased risk of security breaches if the feature is misconfigured or accessible to untrusted users.
• Potential compliance violations if the unauthorized actions result in data exposure or policy violations.

The impact depends on your configuration and whether lower-trust input can access the vulnerable feature. If exploited, it could lead to unauthorized changes or access within your system.

Compliance Impact

This vulnerability could impact compliance with standards and regulations that require strict access controls and data protection, such as GDPR and HIPAA.

• GDPR: Unauthorized access or actions could lead to the exposure of personal data, violating GDPR's requirements for data protection and access control. This may result in non-compliance and potential fines.
• HIPAA: If the vulnerability allows unauthorized access to protected health information (PHI), it could violate HIPAA's Security Rule, which mandates safeguards for electronic PHI. Non-compliance could lead to penalties.
• Other standards: The vulnerability may also affect compliance with frameworks like ISO 27001, which requires proper authorization and access control mechanisms to protect sensitive information.

To maintain compliance, it is critical to apply the patch (version 2026.6.8 or later) and follow recommended hardening practices, such as restricting the feature to trusted operators and limiting allowlists.

Mitigation Strategies

To mitigate this vulnerability, follow these immediate steps:

• Upgrade OpenClaw to version 2026.6.8 or later, as this version contains the patch for the authorization bypass vulnerability.
• If upgrading is not immediately possible, restrict the OpenAI-compatible HTTP model override feature to trusted operators only. Disable the feature entirely if it is not necessary for your use case.
• Implement network-level controls to limit access to OpenClaw endpoints. Use firewalls or access control lists to restrict traffic to trusted sources.
• Review and harden your OpenClaw configuration. Ensure that allowlists are properly configured and avoid sharing Gateways between untrusted users.
• Monitor your system for signs of exploitation, such as unauthorized actions or unusual activity from lower-trust callers.
