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.

Ein Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um beliebigen Code auszuführen, erweiterte Berechtigungen – sogar Administratorrechte – zu erlangen, Daten zu manipulieren, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, einen Denial-of-Service-Zustand herbeizuführen oder andere, nicht näher spezifizierte Angriffe durchzuführen.
- GHSA-4w7m-58cg-cmffOpenClaw: Leaf subagents could steer sibling sessions across sandbox boundaries2026-03-13ghsa · osvUS
## 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.
