Affected: Homebrew: openclaw-cli

### Summary

Workspace .env CLOUDSDK_PYTHON could influence Gmail setup gcloud execution. In affected versions, a workspace `.env` in a repository opened by a trusted operator could influence which Python runtime `gcloud` used through `CLOUDSDK_PYTHON`.

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 run setup through an unintended local Python path. 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 `2026.5.2`.

### Mitigations

run Gmail setup from trusted workspaces and clear workspace env overrides 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.

Affected: OpenClaw

OpenClaw before 2026.5.2 contains an environment variable injection vulnerability allowing workspace .env files to influence Python runtime selection through CLOUDSDK_PYTHON during Gmail setup gcloud execution. Attackers with repository access can manipulate the CLOUDSDK_PYTHON variable to execute setup through unintended local Python paths, potentially enabling arbitrary code execution.
