## Verdict summary
**Blocked & quarantined** — Reason receives credentials that can grant access to the user's provider accounts until those tokens expire.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 0.2.383
- **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.

Source inspection confirms default-on forwarding of saved third-party access tokens to Reason without an affirmative recipient-specific opt-in. This is credential exfiltration behavior and warrants blocking publication.

## Security analysis

### Published attack-surface review

- **Summary:** The CLI forwards saved third-party service access tokens to Reason's local-subscription service by default.

- **Trigger:** Starting a Reason session while the default local-login setting is enabled.

- **Impact:** Reason receives credentials that can grant access to the user's provider accounts until those tokens expire.

- **Evidence paths:** .lpm-inspection-ht3azD/0-8788a6cc2361.txt

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T07:51:29.659Z

### AI review details

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

- **Mechanism:** The worker reads provider login data and submits updated access tokens to the local-subscription route without an affirmative opt-in.

- **Attack narrative:** The embedded CLI code defaults local-login forwarding on. During session startup it reads saved provider credentials and sends access tokens to Reason's local-subscription route. The CLI help discloses that Reason receives these tokens and says refresh tokens are not sent; that disclosure does not establish affirmative consent to forward saved third-party credentials.

- **Rationale:** Source inspection confirms default-on forwarding of saved third-party access tokens to Reason without an affirmative recipient-specific opt-in. This is credential exfiltration behavior and warrants blocking publication.

- **Files touched:** bin/ara

### Review decision

- **Verdict:** Malicious

- **Confidence:** 92.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The embedded CLI help says local-login forwarding is on by default and that Reason receives saved provider access tokens., The runtime defaults an unspecified local-login setting to enabled., When enabled, the worker reads local provider credentials and submits changed credentials through its local-subscription client call., The session startup path activates that transfer when local logins are enabled., The inspected credential source includes access tokens from saved provider login data; the client sends the credential object to the local-subscription route.

- **Evidence against:** The help says this feature sends access tokens, not refresh tokens.

## Affected versions and remediation

This report applies to @reason-machines/cli-darwin-arm64@0.2.383.

- Avoid installing @reason-machines/cli-darwin-arm64@0.2.383. 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.

                                 on this computer (on by default; off with an API key).
                                 Reason gets each login's current access token, never
                                 its refresh token.

  --keep-awake on|of
