Summary
OpenClaw's ACP child sessions inherit subagent security envelope constraints
Details

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.

Fix Commit(s)

  • 31160dc069b7cc5d833b39c53736a41ad3befda2

Verification

  • The fix commit is contained in the public v2026.4.22 tag.
  • openclaw@2026.4.22 is published on npm and the compiled package contains the fix.
  • Focused regression coverage for this path passed before publication.

OpenClaw thanks @zsxsoft, @qclawer, and @KeenSecurityLab for reporting.
