AI Security Review

scanned 10d ago · by lpm-firewall-ai

The postinstall tracker automatically sends identifying project or workspace context without a visible consent gate. Its package-branded telemetry recipient and installation-attribution purpose do not establish the unrelated-collector behavior required for a block.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Installing the package through npm, which runs its postinstall hook.

Impact

Project, workflow, or workspace identifiers may be disclosed during installation without an explicit installer action to send them.

Mechanism

The hook detects installation context, serializes the details into a telemetry event, and posts it to the package telemetry endpoint or its fallback; the tracker has no visible opt-in check.

AI rationale

Network endpoints2

Decision evidence

public snapshot

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

Evidence for warning

The postinstall hook runs the installation tracker.
The tracker collects GitHub repository and workflow names, and can collect a Gitpod workspace identifier.
The installation event serializes the detected installation details and labels the event as npm lifecycle tracking.
The tracker sends the installation payload to the package telemetry endpoint, with a fallback endpoint.
The tracker makes an HTTPS request to the selected endpoint.

Evidence against

The recipient is a package-branded telemetry service, and the reported information is installation context rather than credentials.
