GHSA-474h-prjg-mmw3: OpenClaw: Sandboxed sessions_spawn(runtime="acp") bypassed sandbox inheritance and allowed host ACP initialization

highCVSS 3.1 8.0

Summary Sandboxed sessionsspawn(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".

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
