`OpenClaw: session_status` let sandboxed subagents access parent or sibling session state
### Summary The built-in `session_status` tool did not enforce the intended session-visibility boundary. A sandboxed subagent could supply another session's `sessionKey` and inspect or modify state outside its own sandbox scope. ### Impact This allowed a sandboxed child session to read parent or sibling session data and, in affected releases, update the target session's persisted model override. ### Affected versions `openclaw` `<= 2026.3.8` ### Patch Fixed in `openclaw` `2026.3.11` and included in later releases such as `2026.3.12`. Session visibility checks now enforce the sandbox boundary before reading or mutating session state.
