CLI to create multi-package Lerna projects with TypeScript and React

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

No concealed payload, self-dependency chain, or malicious install-time control-surface mutation was found. However, automatic command telemetry exports developer and project metadata when a token is present, leaving a real privacy and data-egress concern.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Run a startup CLI command in an environment where a Datadog client token is available.

Impact

Project and developer identity metadata may leave the machine without a per-command consent prompt.

Mechanism

Command telemetry posts Git-derived context to Datadog.

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Installation automatically runs a postinstall script that invokes patch-package in the consumer project.
CLI telemetry collects repository, branch, hostname, and Git user identity.
Telemetry posts the collected context as JSON to Datadog whenever a client token is available.
The command base class records telemetry for command starts and finishes.

Evidence against

The postinstall code applies the included patch and removes its temporary pnpm symlinks in a finally block.
The bundled patch only changes jsdom property configurability; no payload download or secret harvesting was found.
No runtime dependency on @servicetitan/startup or opaque remote code-loading chain was found.
The reviewed wrapper, task, dev-server, CLI, and clean-command paths implement ordinary CLI and build-tool behavior.
