### Summary
A Windows `system.run` approval-integrity mismatch in the `cmd.exe /c` path could allow trailing arguments to execute while approval/audit text reflected only a benign command string.

This requires an authenticated operator context using the approvals flow and a trusted Windows node.

### Affected Packages / Versions
- Package: `openclaw` (npm)
- Latest published vulnerable version (as of 2026-02-21): `2026.2.19-2`
- Vulnerable range: `<=2026.2.19-2`
- Patched version (planned next release): `2026.2.21`

### Attack Scenario
1. An authenticated operator approval is created for a benign command text (for example, `echo`).
2. A `system.run` request uses `cmd.exe /c` with extra trailing arguments.
3. Prior behavior could bind approval/audit text to the benign command while still executing the full argument tail on the node.

### Impact
- Local command execution on the trusted Windows node process account.
- Approval/audit command text integrity mismatch.

### Fix
- Canonicalize the full command tail after `cmd.exe /c`.
- Reuse one shared command canonicalization/validation path for validation, approval matching, and execution/audit text.
- Add regression coverage for trailing-argument smuggling and approval binding.

### Fix Commit(s)
- `6007941f04df1edcca679dd6c95949744fdbd4df`

### Release Process Note
`patched_versions` is pre-set to the planned next release (`2026.2.21`). Once that npm release is live, this advisory can be published directly.
