Description
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.
