Reason CLI native binary for linux-arm64-musl

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The source confirms conditional forwarding of saved coding-agent access tokens to a Reason service request, with the setting enabled by default and described in CLI help. The native executable is only partially analyzed, leaving behavior and consent unresolved; manual review is warranted.

Static reason

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

Trigger

A user connects or runs the CLI with local logins enabled; the runtime defaults that setting to enabled when unspecified.

Impact

Local account access tokens may be disclosed to the Reason service; the full impact cannot be determined from the available inspection.

Mechanism

The runtime reads saved agent credentials and submits them through the localSubscription client method. The CLI help discloses token forwarding, but the inspected evidence does not resolve recipient consent or the native executable's full behavior.

AI rationale

Decision evidence

public snapshot

AI called this Manual Review at 78.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest identifies this as a platform-specific Reason CLI package.
The runtime reads saved credentials for local coding-agent accounts.
When local logins are enabled, the runtime passes those credentials to a localSubscription request.
The setting is defaulted to enabled when no value is supplied.
The CLI help says Reason receives each login's current access token; this makes the transfer visible but does not resolve recipient consent.
The native executable analysis is limited to embedded source windows and cannot establish its full behavior.

Evidence against

The package's CLI help describes local logins as a Sessions feature and provides an option to turn them off.
