AI Security Review
scanned 6d ago · by lpm-firewall-aiInspected source establishes an active transfer of saved third-party access tokens to a package-selected Reason API endpoint, with forwarding enabled by default on the ordinary connection path. This is concrete credential exfiltration, so the package should be blocked.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
A user runs persistent connection setup without specifying the local-login setting or an API key; the setting defaults on and forwarding starts with the worker.
Impact
The recipient obtains active credentials that can authorize requests to the corresponding provider accounts.
Mechanism
The worker reads provider credentials from local authentication stores and posts provider access-token records to the local subscription endpoint.
Attack narrative
During ordinary persistent connection setup, the package defaults local-login forwarding on when no setting or API key is supplied. The worker reads saved third-party access tokens and posts them to Reason's local subscription endpoint. The source does not establish recipient-specific consent before this transfer; connecting to Reason does not itself authorize disclosure of credentials issued by other providers.
AI rationale
Inspected source establishes an active transfer of saved third-party access tokens to a package-selected Reason API endpoint, with forwarding enabled by default on the ordinary connection path. This is concrete credential exfiltration, so the package should be blocked.

Decision evidence
public snapshotAI called this Malicious at 96.0% confidence as Malware with low false-positive risk.
Evidence for block
- The worker reads existing provider credentials from local authentication files, including Claude, Codex, Grok, and OpenCode stores, then selects their access tokens.
- For each new provider record, the worker passes the access token to its local subscription API.
- Persistent connection defaults local logins on when the setting is absent and no API key is supplied; worker startup then runs the forwarding routine.
- The API client posts the request body to the local subscription route at the production Reason API origin.

Affected versions and remediation
This report applies to @reason-machines/cli-linux-arm64-musl@0.2.363.
See all versions of @reason-machines/cli-linux-arm64-musl for other recorded verdicts.
- Avoid installing @reason-machines/cli-linux-arm64-musl@0.2.363. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
Evidence last updated: .
Think this verdict is wrong? Dispute it on GitHub or read how reports are produced.
