@reason-machines/cli-win32-x64@0.2.454
Reason CLI native binary for win32-x64
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe inspected executable source supports conditional forwarding of saved third-party access tokens, enabled by default during worker setup. The recipient and consent boundary remain unresolved, and the manifest contains no install hook, so downgrade to a warning.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
A user connects or runs a Reason worker with local logins enabled; the default is on unless the setting is explicitly provided.
Impact
Saved third-party access tokens may be disclosed to the configured Reason service, creating credential exposure risk.
Mechanism
The worker reads saved credentials and environment values, reduces collected records to provider, access token, and expiry, then calls the local-subscription API. The configured recipient and effective recipient-specific consent are not established by the inspected excerpts.
AI rationale
The inspected executable source supports conditional forwarding of saved third-party access tokens, enabled by default during worker setup. The recipient and consent boundary remain unresolved, and the manifest contains no install hook, so downgrade to a warning.
Evidence
.lpm-inspection-0hIhkD/0-ccf4e3c76af7.txtbin/reason.exeClaude, Codex, Grok, OpenCode, and local-agent credential files
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The CLI gathers existing Claude, Codex, Grok, OpenCode, and local agent credentials; the forwarding helper sends access-token data to its local-subscription API.
- The worker calls that helper automatically when local logins are enabled; setup defaults that setting to on unless explicitly set.
- The CLI help discloses that Reason receives current access tokens, but this does not establish affirmative consent to transfer saved third-party credentials.
Evidence against
- package.json has no lifecycle scripts, so this behavior is not triggered by package installation.
- The executable analysis is bounded and does not establish the specific API host or full native-code behavior; the configured service recipient remains unresolved.
