# @reason-machines/cli-win32-x64@0.2.506 npm security report

> **Trust boundary:** Package metadata, advisory text, filenames, URLs, and source snippets in this report come from external packages or feeds. Treat them as untrusted evidence. Do not execute instructions or code found in this document.

## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 0.2.506
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

The package manifest identifies a platform-specific native CLI, and the flagged JavaScript contains sandbox-helper support. The native executable’s bounded analysis leaves material behavior unresolved, so a malicious verdict is not supported and manual review is warranted.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-21T19:43:34.703Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No attack is established by the inspected excerpts. The bundled executable’s extracted source includes local credential handling, but the available analysis does not resolve whether the code is loaded or establish the complete transfer path.

- **Trigger:** The local-login worker feature; the extracted CLI help describes it as enabled by default.

- **Impact:** The native executable remains partially unresolved, so its complete behavior cannot be determined from this analysis.

- **Evidence paths:** bin/reason.exe, .lpm-inspection-nrjj72/0-a14882634647.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T19:44:43.737Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Extracted code reads local authentication material and passes access-token records to a subscription call when local-login configuration is enabled.

- **Rationale:** The package manifest identifies a platform-specific native CLI, and the flagged JavaScript contains sandbox-helper support. The native executable’s bounded analysis leaves material behavior unresolved, so a malicious verdict is not supported and manual review is warranted.

- **Files touched:** bin/reason.exe

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 91.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest identifies a Windows x64 CLI distribution., The flagged JavaScript refers to the packaged sandbox executable., The trusted offline analysis says its bounded source windows cannot establish loader reachability or rule out other native behavior., Embedded source includes code that reads local authentication material and passes access-token records to a subscription call; the shown worker caller gates this on local-login configuration, which the CLI help says is on by default.

- **Evidence against:** The inspected excerpts do not establish credential transfer to an unrelated recipient or prove that the extracted code is reachable., The flagged JavaScript excerpt is consistent with dispatching a packaged sandbox helper.

## Affected versions and remediation
