  "details": "## Summary\nIn 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.\n\n## Impact\nA 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.\n\n## Affected Packages and Versions\n- Package: `openclaw` (npm)\n- Affected versions: `\u003c= 2026.3.8`\n- Fixed in: `2026.3.11`\n\n## Technical Details\nLeaf subagents retained the `subagents` tool, and subagent control requests were authorized against the parent requester scope rather than the caller\u0027s own spawned descendants. The control path prevented only self-targeting, not cross-sibling steering.\n\n## Fix\nOpenClaw now removes `subagents` control access from leaf subagents by default, scopes subagent control to the caller\u0027s own descendants, and rejects `steer` and `kill` requests that target runs outside that descendant tree. The fix shipped in `openclaw@2026.3.11`.\n\n## Workarounds\nUpgrade to `2026.3.11` or later.",
