Description

OpenClaw: Sandboxed sessions_spawn(runtime="acp") bypassed sandbox inheritance and allowed host ACP initialization

Summary

Sandboxed sessions_spawn(runtime="acp") could bypass sandbox inheritance and initialize host-side ACP runtime. The fix now fail-closes ACP spawn from sandboxed requester sessions and rejects sandbox="require" for runtime="acp".

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version at triage time: 2026.3.1 (March 2, 2026)
  • Vulnerable range: <=2026.3.1
  • Patched release: 2026.3.2 (released)

Technical Details

  • Root cause: runtime="subagent" enforced sandbox inheritance, while runtime="acp" did not enforce equivalent sandbox/runtime checks.
  • Security impact: sandbox-boundary bypass into host-side ACP initialization.
  • Fixed behavior:
  • deny ACP spawn when requester runtime is sandboxed
  • deny sessions_spawn with runtime="acp", sandbox="require"
  • align sandboxed prompt guidance to avoid advertising blocked ACP paths
