| Summary | OpenClaw: Leaf subagents could steer sibling sessions across sandbox boundaries ## 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. |
