Reason CLI native binary for linux-arm64

AI Security Review

scanned 7d ago · by lpm-firewall-ai

The package has no install hook, but its user-started worker defaults to forwarding discovered provider login tokens to the Reason service. Because the handoff is disclosed as a product feature yet enabled by default without a recipient-specific consent gate, warn rather than block.

Static reason

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

Trigger

The user connects a persistent worker with `reason connect`, then the worker starts.

Impact

Provider session tokens are disclosed to the Reason service, creating conditional exposure of those accounts.

Mechanism

The worker reads saved provider login data and sends each discovered login through its local-subscription request to the configured Reason API.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package manifest contains no lifecycle script.
The worker reads existing Claude, Codex, and Grok login data, including access tokens.
Connecting the worker enables local login handoff by default; its startup loop passes each discovered login to a local-subscription request.
That request goes to the Reason API, whose production endpoint is package-aligned.

Evidence against

The CLI describes these logins as serving the user's Reason sessions, and the handoff is part of the user-started worker connection.
The flagged agent configuration excerpts show local path handling, an explicit Playwright skill-install command, and retired MCP configuration checks; they do not establish malicious behavior. Source-similarity hints alone are not proof.
