## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 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:** 0.3.1
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The postinstall collector sends Git identity and installation telemetry automatically unless opted out. This supports a warning for data disclosure, but the fixed first-party destination and absence of credential theft or execution behavior do not establish a block-worthy attack.

## Latest scan

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:** The postinstall hook automatically collects installation telemetry and may include the consumer's Git display name and email. It sends the event to a fixed first-party endpoint.

- **Trigger:** Installing the package with lifecycle scripts enabled, unless a supported telemetry opt-out is set.

- **Impact:** Personal Git identity may be disclosed to the package vendor without an affirmative opt-in.

- **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/git-context.cjs, install/policy.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T03:30:23.311Z

### AI review details

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

- **Mechanism:** The collector reads Git configuration, adds identity and installation details to an event, and posts it over HTTPS.

- **Rationale:** The postinstall collector sends Git identity and installation telemetry automatically unless opted out. This supports a warning for data disclosure, but the fixed first-party destination and absence of credential theft or execution behavior do not establish a block-worthy attack.

- **Files touched:** package.json, install/postinstall.cjs, install/collector.cjs, install/git-context.cjs, install/policy.cjs

- **Network endpoints:** https://threadplane.ai/api/growth/collect/v1/install

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package runs a postinstall script that invokes the collector., The collector sends installation events to a fixed Threadplane endpoint., The event includes an installation identity and package and environment details., The collector reads Git identity, including a configured display name and email, and adds it to the event., Collection is disabled by supported opt-out environment variables, but otherwise runs automatically.

- **Evidence against:** The endpoint is package-aligned, and the collector validates the package name and version before collecting., The source shows no credential harvesting, remote code execution, or consumer project policy mutation.
