## Verdict summary
**Blocked & quarantined** — The Reason service receives usable current access tokens for third-party coding-tool accounts; refresh tokens are omitted.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 0.2.376
- **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 has a default active path that transfers saved third-party access tokens to the product API without recipient-specific affirmative consent. The sandbox-runtime similarity and process-execution signals are not the basis for this decision.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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 coding-tool access tokens and sends them to its configured Reason API for local-subscription checks. This runs by default when its worker starts with the default local-login setting.

- **Trigger:** Starting a worker while local logins are enabled, which is the default when the setting is omitted.

- **Impact:** The Reason service receives usable current access tokens for third-party coding-tool accounts; refresh tokens are omitted.

- **Evidence paths:** .lpm-inspection-ZY2sKB/0-1f8a61682da2.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T01:27:42.302Z

### AI review details

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

- **Mechanism:** The CLI reads saved credentials and repeatedly sends records containing provider, access token, and expiry to the local-subscription API route. No affirmative recipient-specific consent gate appears in the transfer path.

- **Attack narrative:** The CLI's worker collects saved access tokens from coding-tool credential stores and sends them to its configured Reason API for local-subscription checks. This is enabled by default. An off switch and disclosure do not provide affirmative consent to send saved third-party tokens to this recipient.

- **Rationale:** The native CLI has a default active path that transfers saved third-party access tokens to the product API without recipient-specific affirmative consent. The sandbox-runtime similarity and process-execution signals are not the basis for this decision.

- **Files touched:** bin/ara, .lpm-inspection-ZY2sKB/0-1f8a61682da2.txt

- **Network endpoints:** /app/local-runtime/local-subscription at the configured apiOrigin

### Review decision

- **Verdict:** Malicious

- **Confidence:** 97.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The flagged sandbox runtime location filters selected project paths, including agent directories; it does not establish the credential behavior., The native CLI defaults an omitted local-login setting to enabled., The CLI reads existing credentials from the system keychain and coding-agent credential files; the data includes access tokens., When local logins are enabled, worker startup repeatedly submits collected records through the local-subscription API call., The client sends those records to \`/app/local-runtime/local-subscription\` at its configured API origin., The CLI describes local-login use and offers an off setting, but access-token submission is enabled by default; the submitted record omits refresh tokens.

- **Evidence against:** The code submits current access tokens, not refresh tokens, and provides a local-logins off setting.

## Affected versions and remediation

This report applies to @reason-machines/cli-darwin-arm64@0.2.376.

- Avoid installing @reason-machines/cli-darwin-arm64@0.2.376. 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.
