Affected: OpenClaw

OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability allowing leaf subagents to access the subagents control surface and resolve against parent requester scope instead of their own session tree. A low-privilege sandboxed leaf worker can steer or kill sibling runs and cause execution with broader tool policies by exploiting insufficient authorization checks on subagent control requests.

 https://vulnerability.circl.lu/vuln/ghsa-4w7m-58cg-cmff GHSA-4w7m-58cg-cmff — OpenClaw: Leaf subagents could steer sibling sessions across sandbox boundaries 2026-09-28T12:30:12.146576+00:00

Affected: npm: openclaw

## 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.
