OpenClaw before 2026.8.1 lets users run system commands

CVE-2026-100552 · published 18 days ago
Summary

The OpenClaw npm package released before version 2026.8.1 fails to keep low‑trust chat sessions from accessing the underlying command‑line and file tools. This means a user could bypass the intended restrictions and execute native commands or modify files, depending on the server’s permissions. Upgrade to version 2026.8.1 or later to enforce the proper tool allowlist.

What to do
  • Update openclaw openclaw to version 2026.8.1 or later.

Original advisory text
OpenClaw before 2026.8.1 Policy Bypass via Native Tools
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.
