概要
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.

NVD の説明
OpenClaw before 2026.4.22 contains a security envelope constraint bypass vulnerability allowing restricted subagents to spawn ACP child sessions that fail to inherit depth, child-count limits, control scope, or target-agent restrictions. Attackers can exploit this by spawning child sessions that bypass subagent-only constraints, potentially escalating privileges or accessing restricted resources.
