## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 18 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 2.25.1
- **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

The flagged command is used by the host resource detector, and the inspected exporter logs spans to console rather than sending them to an unrelated endpoint. I cannot certify clean because the required @netlify/types main file is empty and the citation service cannot issue a valid citation for it.

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 concrete attack surface was identified in the inspected runtime. Clean status remains unresolved because a required dependency source file is empty and cannot be cited by the source tool.

- **Trigger:** Importing the exposed instrumentation subpath starts its OpenTelemetry SDK; no malicious trigger was identified.

- **Impact:** No unrelated network transfer, credential collection, or destructive behavior was established from the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-26T12:30:28.437Z

### AI review details

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

- **Mechanism:** The inspected instrumentation reads host identifiers for resource attributes and writes serialized spans to console output, with request header collection skipped.

- **Rationale:** The flagged command is used by the host resource detector, and the inspected exporter logs spans to console rather than sending them to an unrelated endpoint. I cannot certify clean because the required @netlify/types main file is empty and the citation service cannot issue a valid citation for it.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 76.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest routes the package root, server API, and instrumentation subpath to the inspected runtime files., The package’s prepare script sets up Husky hooks; its published lifecycle scripts do not show a registry install hook., The server entry handles requests through the selected function handler., The instrumentation bundle’s host detector reads a platform machine identifier, consistent with host resource detection., Its trace exporter serializes spans to console output; the instrumentation starts an SDK with header collection skipped and Netlify service metadata., The inspected @netlify/types manifest has no install lifecycle script.

- **Evidence against:** The declared @netlify/types main file was empty. The citation service could not issue an exact citation for an empty file, so required clean citation coverage could not be completed.

## Affected versions and remediation
