Summary
OpenClaw: system.run approvals did not bind PATH-token executable identity, enabling post-approval executable rebind
Details

Summary

For host=node runs, approvals validated command context but did not pin executable identity for non-path-like argv[0] tokens (for example tr). If PATH resolution changed after approval, execution could run a different binary.

Impact

A previously approved action could execute a different executable than the operator approved.

Fix

Node system.run approvals now require immutable systemRunPlan data, and path-token commands are pinned to canonical executable identity (realpath) across approval and execution.
