# evals@2.11.1 npm security report

## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 15 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 2.11.1
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The package’s runtime onboarding flow sends event telemetry linked by a stable anonymous ID without an apparent opt-out or CLI disclosure, so this merits a warning. The inspected payload is limited to event names and that ID, and the install hook only prints a message.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 87.0%
- **Started:** 2026-10-30T21:33:16.083Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Runtime telemetry sends onboarding events and a stable anonymous identifier to Arize.

- **Trigger:** The user selects an agent in the CLI onboarding flow; the prompt also requests an auth-opened event before OAuth.

- **Impact:** Arize can associate onboarding actions over time for the same anonymous client ID; inspected telemetry does not include credentials or project contents.

- **Evidence paths:** analytics.js, cli.js, onboarding-prompt.md

- **Review source:** ai\_review

- **Reviewed:** 2026-10-30T21:33:59.809Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The analytics helper posts an allowlisted event name and anonymous client ID to the configured endpoint. No opt-out was found, and the CLI does not disclose this tracking in its interface.

- **Rationale:** The package’s runtime onboarding flow sends event telemetry linked by a stable anonymous ID without an apparent opt-out or CLI disclosure, so this merits a warning. The inspected payload is limited to event names and that ID, and the install hook only prints a message.

- **Files touched:** ~/.arize/anon\_client\_id

- **Network endpoints:** https://app.arize.com/api/analytics/npx-evals

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Runtime analytics posts allowlisted onboarding event names to Arize’s analytics endpoint., The analytics payload contains the event name and a stable anonymous client ID., The CLI sends an analytics event after the user selects an agent and starts the onboarding flow.

- **Evidence against:** The postinstall script only prints a message; it does not contact the network., The analytics code limits events and does not include credentials or project contents in its payload., The onboarding prompt describes an anonymous funnel ping before OAuth, and the remaining setup is tied to the onboarding flow.
