BREW-openclaw-cli-CVE-2026-35650 — OpenClaw has Inconsistent Host Exec Environment Override Sanitization

Affected: Homebrew: openclaw-cli

## Summary Gateway host exec env override handling did not consistently apply the shared host environment policy, so blocked or malformed override keys could slip through inconsistent sanitization paths.

## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2`

## Fix Commit(s) - `7abfff756d6c68d17e21d1657bbacbaec86de232`

## Release Status The fix shipped in `v2026.3.22` and remains present in `v2026.3.23` and `v2026.3.23-2`.

## Code-Level Confirmation - src/infra/host-env-security.ts now provides one shared sanitizer and fail-closed diagnostics for blocked or malformed override keys. - src/agents/bash-tools.exec.ts and src/node-host/invoke-system-run.ts both route env overrides through the shared sanitizer before execution.

OpenClaw thanks @zpbrent for reporting.

OpenClaw before 2026.3.22 contains an environment variable override handling vulnerability that allows attackers to bypass the shared host environment policy through inconsistent sanitization paths. Attackers can supply blocked or malformed override keys that slip through inconsistent validation to execute arbitrary code with unintended environment variables.
