CVE-2026-53864: OpenClaw: Host environment sanitizer missed two Node.js control variables

Host environment sanitizer missed two Node.js control variables. In affected versions, a lower-trust env source such as a workspace .env, tool env override, or skill env block could pass Node.js control variables through the shared sanitizer.

This advisory is scoped to the named feature and configuration. It does not change OpenClaw’s trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed.
