OpenClaw before 2026.8.1 Policy Bypass via Native Tools

Type: advisorySources: OSV

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.
