Details

Summary

OpenShell mirror mode can convert untrusted sandbox files into explicitly enabled workspace hooks and execute them on the host during gateway startup

Current Maintainer Triage

  • Status: narrow
  • Normalized severity: medium
  • Assessment: Real on shipped <=2026.3.22 OpenShell mirror sync, but exploit needs mirror mode plus hooks enabled plus explicit hook opt-in plus restart, so high is overstated even though the direct fix shipped in v2026.3.28.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version: 2026.3.31
  • Vulnerable version range: <=2026.3.24
  • Patched versions: >= 2026.3.28
  • First stable tag containing the fix: v2026.3.28

Fix Commit(s)

  • c02ee8a3a4cb390b23afdf21317aa8b2096854d1 — 2026-03-25T19:59:07Z

Release Process Note

  • The fix is already present in released version 2026.3.28.
  • This draft looks ready for final maintainer disposition or publication, not additional code-fix work.

Thanks @tdjackey for reporting.
