Description

OpenClaw's ACP child sessions inherit subagent security envelope constraints

Summary

ACP child sessions inherit subagent security envelope constraints.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.4.21
  • Fixed version: 2026.4.22

Impact

A restricted subagent spawning an ACP child session could fail to carry forward subagent-only constraints such as depth, child-count limits, control scope, or target-agent restrictions.

Fix

ACP spawn now resolves and persists child subagent envelope fields, enforces maximum depth and active-child caps, and applies the inherited control scope to child ACP sessions.
