@servicetitan/startup@39.3.0

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

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

This is a real conditional data-exfiltration surface rather than an opaque payload, but it is tied to user-invoked CLI use and a configured vendor telemetry token. The automatic patch hook is transparent and locally scoped.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

A user runs a startup CLI command with DATADOG_CLIENT_TOKEN set or the optional secrets package available.

Impact

Git username, email, repository, branch, hostname, platform, and command metadata can leave the machine.

Mechanism

Conditional telemetry collection and HTTPS POST to Datadog.

AI rationale

Evidence

Network endpoints1

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The install hook runs patch-package against the consumer project.
CLI telemetry collects the Git username, email, repository, branch, hostname, and platform.
When a Datadog client token is available, telemetry posts that context to Datadog.
Every recorded CLI command starts this telemetry flow.

Evidence against

The network request is conditional on a configured or optional-package Datadog token.
The postinstall patch is a visible jsdom compatibility patch and its temporary symlinks are removed.
No self-dependency, concealed payload, agent-control write, or install-time network request was found.
