MMI Future CLI — the org dev toolbox and shared cross-IDE engine for every registry-declared MMI coding surface.

AI Security Review

scanned 27d ago · by lpm-firewall-ai

Running the CLI can collect a GitHub credential and transmit it to the package's default Hub service. It also sends command telemetry automatically.

Static reason

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

Trigger

A user invokes mmi-cli and runs a command that obtains Hub authentication.

Impact

The endpoint receives a GitHub bearer token that may grant access to the user's GitHub resources.

Mechanism

GitHub token collection followed by an authenticated POST to the default Hub endpoint.

Attack narrative

The executable loads its main bundle on user invocation. That bundle obtains GH_TOKEN, GITHUB_TOKEN, or the output of gh auth token, then sends the token in an Authorization header to a default AWS API Gateway Hub endpoint. The same command path emits telemetry by default. This is concrete credential transmission to a package-controlled external service.

AI rationale

The package directly harvests an available GitHub credential and transmits it to an opaque external endpoint. The absence of an install hook does not mitigate credential exfiltration when the advertised CLI is run.
