OpenClaw Tool Policy Bypass in Codex Runtime

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
OpenClaw (npm package 'openclaw') before 2026.8.1 does not correctly enforce per-chat tool policies for Codex app-server runtime tools. A conversation-level tools.allow rule filtered OpenClaw tools but did not restrict the shell, process, file, and patch tools owned by the Codex runtime. When a lower-trust conversation was assigned to a Codex runtime and restricted with a per-chat tool allowlist, a participant able to trigger that agent could still reach native command and file tools, bypassing the configured allowlist. The practical impact depends on the runtime's host permissions and sandbox configuration. The issue is fixed in 2026.8.1.

Executive Summary

OpenClaw before version 2026.8.1 fails to enforce per-chat tool policies correctly. It allows bypassing conversation-level tool allowlists by granting access to native command and file tools like shell, process, file, and patch tools owned by the Codex app-server runtime. This happens because the filtering does not restrict these native tools even when a policy is set.

Detection Guidance

To detect this vulnerability, check the installed version of the OpenClaw npm package. Run 'npm list openclaw' to verify if the version is below 2026.8.1. If it is, the system is vulnerable.

Impact Analysis

The impact depends on the runtime's host permissions and sandbox configuration. An attacker could execute native commands or access files on the host system, potentially leading to unauthorized data access, modification, or system compromise. The severity is high due to potential effects on confidentiality, integrity, and availability.

Compliance Impact

The vulnerability could potentially impact compliance with GDPR or HIPAA if the affected tools (shell, process, file, patch) are used to access or modify sensitive data without proper authorization. Unauthorized access to native command and file tools may lead to data breaches or unauthorized data processing, which are key concerns under GDPR and HIPAA. The practical impact depends on the runtime's host permissions and sandbox configuration.

Mitigation Strategies

Immediately upgrade OpenClaw to version 2026.8.1 or later using 'npm install openclaw@latest'. Before upgrading, route restricted chats to an agent runtime without native host tools or disable those tools at the agent boundary.
