Summary

In affected versions of openclaw, sandboxed leaf subagents could still access the subagents control surface and resolve against the parent requester scope instead of remaining confined to their own session tree.

Impact

A low-privilege sandboxed leaf worker could steer or kill a sibling run owned by the same requester and cause that sibling to execute with its own broader tool policy. This is a sandbox and session-scope boundary bypass.

Affected Packages and Versions

• Package: openclaw (npm)
• Affected versions: <= 2026.3.8
• Fixed in: 2026.3.11

Technical Details

Leaf subagents retained the subagents tool, and subagent control requests were authorized against the parent requester scope rather than the caller's own spawned descendants. The control path prevented only self-targeting, not cross-sibling steering.

Fix

OpenClaw now removes subagents control access from leaf subagents by default, scopes subagent control to the caller's own descendants, and rejects steer and kill requests that target runs outside that descendant tree. The fix shipped in openclaw@2026.3.11.

Workarounds

Upgrade to 2026.3.11 or later.
