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.

Vulnerability from cvelistv5 – Published: 2026-05-11 16:46 – Updated: 2026-05-11 17:25 X_Open Source

Title

OpenClaw < 2026.4.22 - Security Envelope Constraint Bypass in ACP Child Sessions

Summary

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.

Severity
