# @reason-machines/cli-darwin-x64@0.2.553 npm security report

## Verdict summary
**Blocked & quarantined** — Third-party account credentials are disclosed to the Reason service, potentially allowing access to those accounts.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 0.2.553
- **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The native CLI’s embedded source shows saved third-party credentials flowing into an automatically enabled handover to the Reason API. This is an unconsented disclosure to a recipient separate from the credential providers, so publication should be blocked.

## Latest scan

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:** The native CLI collects saved third-party provider credentials and forwards access values to the Reason API. The handover is enabled by default when the setting is omitted.

- **Trigger:** Starting a connected worker with localLogins enabled; the source defaults that setting to enabled when absent.

- **Impact:** Third-party account credentials are disclosed to the Reason service, potentially allowing access to those accounts.

- **Evidence paths:** .lpm-inspection-J8e0IK/0-770bdff7bf73.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-23T04:11:46.431Z

### AI review details

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

- **Mechanism:** The worker reads saved provider credentials and submits discovered access values in requests to /local-subscription.

- **Attack narrative:** The embedded native code reads credentials from local provider stores, then a recurring handover loop submits access values to the Reason API’s /local-subscription route. The connected-worker startup invokes this handover when localLogins is enabled, and missing configuration defaults it to enabled. The source shows no recipient-specific affirmative consent gate for sending those provider credentials to the Reason service.

- **Rationale:** The native CLI’s embedded source shows saved third-party credentials flowing into an automatically enabled handover to the Reason API. This is an unconsented disclosure to a recipient separate from the credential providers, so publication should be blocked.

- **Files touched:** bin/reason, .credentials.json, auth.json

- **Network endpoints:** /local-subscription

### Review decision

- **Verdict:** Malicious

- **Confidence:** 94.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The manifest identifies this as the Reason CLI native binary package., The native code reads saved provider credentials, including a credential file and Codex API key., A repeating handover loop sends discovered access values through the local-subscription client., When the setting is absent, localLogins defaults to enabled, and the connected worker starts the handover when enabled., The client sends the handover data as the request body to the device-authenticated /local-subscription route.

- **Evidence against:** The offline native analysis is bounded and cannot establish reachability of every embedded source window or the executable’s full behavior.

## Affected versions and remediation

This report applies to @reason-machines/cli-darwin-x64@0.2.553.

- Avoid installing @reason-machines/cli-darwin-x64@0.2.553. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
