Reason CLI native binary for linux-x64

AI Security Review

scanned 6d ago · by lpm-firewall-ai

Source inspection confirms that the CLI forwards saved third-party service access tokens to Reason by default, without a recipient-specific consent gate. This is concrete credential disclosure supporting a block; the manifest itself has no lifecycle scripts.

Static reason

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

Trigger

Starting a CLI session while local login handover is enabled, which is the default when no setting is supplied.

Impact

Reason receives access tokens for the user’s Claude, Codex, Grok, and other supported logins.

Mechanism

The runtime reads local authentication files, extracts current access tokens, and passes them to the Reason local-subscription request.

Attack narrative

When a CLI session starts, the runtime reads saved login data from local provider files, extracts current access tokens, and submits them to Reason’s local-subscription endpoint. This behavior is enabled by default when no local-login setting is supplied. The tokens authenticate to third-party services, and the source does not establish recipient-specific consent to send them to Reason.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The runtime reads saved Claude, Codex, Grok, OpenCode, and Pi login data, then keeps each provider’s access token for handover.
The local login handover sends those access tokens through the Reason client’s local-subscription request to the Reason API.
When the setting is unspecified, local login handover defaults to on and starts with the active session.
The embedded CLI help confirms that local login handover is on by default and that Reason receives each login’s current access token.
The runtime maps `localSubscription` to `/local-subscription` with `device_proof` authentication.

Evidence against

The package has no lifecycle scripts; the transfer runs with the CLI session rather than during installation.
The source sends current access tokens, not refresh tokens.
