Reason CLI native binary for linux-x64-musl

AI Security Review

scanned 5d ago · by lpm-firewall-ai

Inspected source shows a default-enabled path that reads saved third-party access tokens and sends them to Reason's API without an affirmative transfer-specific consent gate. The connection notice and opt-out disclose the feature but do not authorize that recipient-specific transfer.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

The user runs the connection flow and starts the worker with local login forwarding enabled, including when no setting or API key overrides the default.

Impact

Reason receives current access tokens for third-party accounts, creating a risk of unauthorized account access.

Mechanism

The worker reads local provider credential files, extracts access tokens, and submits them as request bodies through Reason's local subscription API.

Attack narrative

The connection flow defaults local login forwarding to enabled unless configuration or an API key overrides it. The worker reads saved credentials for third-party providers and sends their access tokens to Reason's local subscription API. The CLI discloses that these logins serve Reason sessions and provides an off switch, but that disclosure and opt-out do not establish affirmative consent to transfer saved third-party credentials to Reason.

Decision evidence

public snapshot

AI called this Malicious at 95.0% confidence as Malware with low false-positive risk.

Evidence for block

The worker reads saved Claude, Codex, Grok, and other local provider credentials, including access tokens.
When local login forwarding is enabled, the worker sends saved credential objects through the local subscription client.
Connecting defaults local login forwarding to on when no saved setting or API key overrides it.
The CLI sends the request to Reason's configured API, and the local subscription method places the credential object in its request body.
The displayed connection notice says these third-party logins serve Reason sessions and offers an off switch, but does not ask for affirmative consent to send them to Reason.
The manifest identifies this as the Linux native binary package; the reviewed credential flow is in its bundled runtime source.

Evidence against

Forwarding is activated through the user's connection command, and the CLI displays a disclosure and an off switch.
The production recipient is Reason's own API, not an unrelated third-party host; the transferred credentials nevertheless belong to other providers.
