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

The CLI automatically obtains GitHub credentials and transmits them to its Hub service for session exchange. It also sends command telemetry for each command action unless an environment opt-out is set.

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

Running an mmi-cli command that uses Hub authentication; telemetry runs for every command action.

Impact

An existing GitHub credential is disclosed to the external Hub endpoint and can be exchanged for a session.

Mechanism

GitHub-token collection and external bearer-token session exchange.

Attack narrative

When invoked, the package loads its main CLI bundle. That bundle obtains a GitHub token from GH_TOKEN, GITHUB_TOKEN, or the locally authenticated GitHub CLI, then posts it as an Authorization bearer token to the package's default Hub endpoint to create a session. Its command pre-action hook also posts telemetry for each command. The manifest has no install hook, but the credential transfer is concrete runtime exfiltration.

AI rationale

The source directly collects GitHub credentials and sends them to an external service as bearer authentication. The lack of an install hook limits the trigger but does not remove the credential-exfiltration behavior.
