Affected: OpenClaw

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.

 https://vulnerability.circl.lu/vuln/ghsa-q3jj-46pq-826r GHSA-q3jj-46pq-826r — OpenClaw's ACP child sessions inherit subagent security envelope constraints 2026-09-28T19:42:12.492014+00:00

Affected: npm: openclaw

## 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.
