Affected: Homebrew: openclaw-cli

## Summary

Host exec env override sanitization did not fail closed for several package-manager and related redirect variables that can steer dependency fetches or startup behavior.

## Impact

An approved exec request could silently redirect package resolution or runtime bootstrap to attacker-controlled infrastructure and execute trojanized content.

## Affected Component

`src/infra/host-env-security-policy.json, src/infra/host-env-security.ts`

## Fixed Versions

- Affected: `< 2026.3.22` - Patched: `>= 2026.3.22`

## Fix

Fixed by commit `7abfff756d` (`Exec: harden host env override handling across gateway and node`).

OpenClaw before 2026.3.22 contains an incomplete host environment variable sanitization vulnerability in host-env-security-policy.json and host-env-security.ts that allows package-manager environment overrides. Attackers can exploit approved exec requests to redirect package resolution or runtime bootstrap to attacker-controlled infrastructure and execute trojanized content.
