## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 17 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 2.28.0
- **Selected version is latest:** No
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The suspicious scanner signals resolve to OpenTelemetry instrumentation and a platform-specific machine ID detector, with no evidence connecting the detector output to exfiltration or unrelated execution. The package’s explicit instrumentation export and configurable OTEL endpoint fit its stated runtime API purpose.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-30T13:37:50.554Z
- **Finished:** 2026-10-30T13:38:39.584Z
- **Download time:** 519 ms
- **Static scan time:** 2377 ms
- **AI review time:** 46133 ms
- **Total time:** 49030 ms

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:** No attack was identified; the flagged execution is in a machine ID detector, and the separate instrumentation entry initializes OpenTelemetry tracing.

- **Trigger:** Tracing initializes when the explicitly exported instrumentation entry point is imported.

- **Impact:** Runtime observability for Netlify Functions; no malicious collection or execution chain was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-30T13:38:39.584Z

### AI review details

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

- **Mechanism:** OpenTelemetry exports traces using its configured endpoint; the reviewed machine ID detector runs a platform-specific query.

- **Rationale:** The suspicious scanner signals resolve to OpenTelemetry instrumentation and a platform-specific machine ID detector, with no evidence connecting the detector output to exfiltration or unrelated execution. The package’s explicit instrumentation export and configurable OTEL endpoint fit its stated runtime API purpose.

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package is described as Netlify Functions’ runtime API and explicitly exports a separate OpenTelemetry instrumentation entry point., The instrumentation initializes OpenTelemetry tracing and includes function URL and Netlify site attributes, consistent with runtime observability., The flagged command execution reads the macOS platform UUID as part of a machine ID detector; the reviewed code shows no connection from that result to an outbound request., The OpenTelemetry exporter reads its endpoint from standard OTEL environment configuration.

## Affected versions and remediation

This report applies to @netlify/serverless-functions-api@2.28.0.

- Review the evidence and your use of @netlify/serverless-functions-api@2.28.0 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
