Description

Summary

Sandboxed agents could escape exec routing via host=node override.

Affected Packages / Versions

  • Package: openclaw
  • Ecosystem: npm
  • Affected versions: >= 2026.4.5 < 2026.4.10
  • Patched versions: >= 2026.4.10

Impact

A sandboxed agent could request host: "node" and route exec to a remote node instead of the intended sandbox execution path, bypassing the sandbox routing boundary.

Technical Details

The fix blocks sandboxed exec escape to remote node targets and keeps routing aligned with the active sandbox policy.

Fix

The issue was fixed in #63880. The first stable tag containing the fix is v2026.4.10, and [email protected] includes the fix.

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 2026.4.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-736r-jwj6-4w23 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
