Reason CLI native binary for darwin-arm64
AI Security Review
scanned 5d ago · by lpm-firewall-aiSource 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.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
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.
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.
AI 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.

Decision evidence
public snapshotAI called this Malicious at 92.0% confidence as Malware with low false-positive risk.
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.
