AI Security Review

scanned 26d ago · by lpm-firewall-ai

When an invoked command requests Hub authentication, the CLI transmits a local GitHub token to a hard-coded external Hub service. It also sends command telemetry by default on CLI invocation.

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 runs mmi-cli and invokes a command that reaches Hub authentication; telemetry runs before every command.

Impact

The external service receives a reusable GitHub credential, which can grant access within that token's scope.

Mechanism

GitHub token collection followed by a bearer-token POST to a hard-coded external service.

Attack narrative

The executable loads the main bundle when a user runs the CLI. That bundle obtains GH_TOKEN, GITHUB_TOKEN, or the local gh authentication token. For Hub-authenticated operations it sends that credential as a Bearer token to the embedded AWS endpoint. Separately, its global command hook emits telemetry before command actions. This is credential exfiltration to a package-controlled endpoint, not merely an authenticated request to GitHub.

AI rationale

The package directly harvests a local GitHub token and transmits it to a non-GitHub endpoint. The absence of an install hook limits activation to CLI use but does not remove the credential-exfiltration behavior.
