Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.3.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-39pp-xp36-q6mg is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
