### Summary 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. ### Impact When the affected feature is enabled and reachable, this could influence a later Node.js child process or coverage output path when that process is launched under the accepted environment. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path. ### Patched Versions The first stable patched version is `2026.5.26`. ### Mitigations avoid inheriting workspace or tool-supplied env values from untrusted repositories until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.

AI coding agents often install or upgrade packages automatically in npm. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
