AI Security Review

scanned 10h ago · by lpm-firewall-ai

The embedded CLI source establishes default-on collection and transfer of saved AI provider access tokens to the Reason service. This is cross-service credential disclosure and supports blocking publication.

Static reason

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

Trigger

The Reason worker starts with local logins enabled, which is the default.

Impact

The Reason service receives access tokens for separate AI provider accounts without a separate affirmative transfer choice.

Mechanism

The worker reads local provider authentication data and repeatedly submits provider access values in a request body to the Reason service.

Attack narrative

When its worker starts, the CLI reads saved logins for AI providers and sends their access tokens to the Reason API. Local logins are enabled by default, so starting the worker transfers credentials without a separate affirmative choice.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The embedded CLI source reads saved authentication data for AI provider logins and collects provider access values.
Worker startup invokes local-login handover when enabled; the setting defaults to on, and CLI help says Reason receives each login’s current access token.
The handover repeatedly sends provider access data through the local-subscription request body.
The request targets /local-subscription on the production Reason API at https://api.reasonmachines.ai.
The access tokens belong to separate AI provider accounts, and the transfer has no separate affirmative consent gate.

Evidence against

The CLI describes local logins as a feature for running Reason sessions, but the feature is enabled by default. This disclosure does not establish affirmative consent to transfer saved tokens.
