Reason CLI native binary for linux-x64-musl

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The inspected JavaScript shows opt-in forwarding of local provider access tokens to the package's product API. The 99 MB native executable has only bounded embedded-source analysis, so its complete behavior remains unresolved and requires manual review.

Static reason

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

Trigger

Running the packaged CLI activates the native executable; the inspected local-login forwarding path additionally requires localLogins to be true.

Impact

The inspected forwarding path is an explicitly enabled product feature, but the unresolved native behavior prevents a clean determination.

Mechanism

The runtime can read local provider credentials and submit access tokens through the Reason Machines client. Available native analysis only covers bounded embedded-source windows and does not establish the executable's complete behavior.

Decision evidence

public snapshot

AI called this Manual Review at 91.0% confidence as Unknown with medium false-positive risk.

AI review observations

The package is a Linux x64 musl CLI distribution that includes a native executable.
The runtime reads local provider credentials and forwards access tokens only when the explicit localLogins setting is true.
That flow sends provider, access token, and expiry through the client's localSubscription request.
The client uses Reason Machines API endpoints, consistent with the package's product identity.
The offline analysis of the native executable contains bounded embedded-source windows and states that they cannot establish the executable's full behavior.

Evidence against

The inspected credential-forwarding path is gated by localLogins being explicitly true; the inspected code does not establish covert forwarding or an unrelated recipient.
