## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 18 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 39.1.0
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

No evidence shows a self-reinstall chain, hidden payload, or credential theft. The automatic dependency mutation and identifiable telemetry warrant a warning rather than publication blocking.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 85.0%
- **Started:** 2026-09-03T20:04:00.067Z

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:** Installation automatically modifies a dependency in the consumer project. CLI commands can transmit host and Git identity telemetry when a Datadog token is configured.

- **Trigger:** Installing the package activates the patch; running its CLI activates telemetry.

- **Impact:** Changes consumer dependency behavior and sends identifiable development metadata to a third-party telemetry endpoint.

- **Evidence paths:** package.json, src/postinstall.js, patches/jsdom+26.1.0.dev.patch, src/telemetry/telemetry.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-09-03T20:04:59.555Z

### AI review details

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

- **Mechanism:** Postinstall dependency patching and token-gated telemetry upload.

- **Rationale:** No evidence shows a self-reinstall chain, hidden payload, or credential theft. The automatic dependency mutation and identifiable telemetry warrant a warning rather than publication blocking.

- **Files touched:** node\_modules/jsdom/lib/jsdom/browser/Window.js

- **Network endpoints:** browser-intake-datadoghq.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 85.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Its automatic postinstall runs patch-package against the consuming project., The installed patch changes jsdom window, document, location, and top descriptors., User-invoked CLI telemetry sends repository identity, Git user details, hostname, and event data to Datadog when a token is available.

- **Evidence against:** No self-dependency or nested lifecycle chain is declared., The postinstall patch is transparent and limited to one jsdom development patch., The flagged dev-server dynamic require loads a local user-specified proxy configuration.

## Affected versions and remediation

This report applies to @servicetitan/startup@39.1.0.

- Review the evidence and your use of @servicetitan/startup@39.1.0 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.
