Reason CLI native binary for linux-x64-musl

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The source inspection found no verified attack, and the manifest has no lifecycle hooks. The required native executable review is materially limited, so the appropriate verdict is manual review rather than clean or malicious.

Static reason

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

Trigger

Running the packaged native CLI executable; its complete behavior was not established by the available static analysis.

Impact

No concrete harmful effect was verified; the executable's unresolved behavior prevents a reliable clean determination.

Mechanism

The inspected JavaScript includes a gated local-login forwarding path to the Reason client, while the native executable analysis cannot establish full loader reachability or rule out other behavior.

Decision evidence

public snapshot

AI called this Manual Review at 86.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies a Linux x64 musl CLI binary package and declares no lifecycle scripts.
The native executable is a 99 MB ELF; its offline analysis covers bounded embedded source windows and says those windows cannot establish full loader reachability or exclude other behavior.
The inspected JavaScript reads access tokens from local provider credential stores and can pass them to the Reason client through localSubscription; that path is gated by localLogins, which the configuration helper defaults to enabled.
The inspected client configuration points to Reason-branded API hosts. Agent-related source excerpts show workspace path filtering, a user-invoked skill copy function, and Cursor configuration parsing; they do not establish install-time agent control changes.

Evidence against

No concrete attack behavior was established in the inspected source. The native executable remains materially unresolved, so the evidence is insufficient for a clean verdict.
