- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.18.33
- **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.

Source inspection found a normal Playwright browser install hook and user-invoked documentation retrieval. The flagged network and Git behavior is consistent with the package’s knowledge ingestion functionality, with no concrete attack behavior established.

## 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:** No attack was identified. The install hook installs Playwright’s Chromium browser, and exported functions retrieve documentation from caller-selected GitHub repositories, Context7, or caller-provided URLs.

- **Trigger:** Package installation runs the postinstall command; documentation requests occur when consumers call the exported fetch functions.

- **Impact:** The reviewed behavior supports browser setup and documentation ingestion; no credential exposure or harmful install-time mutation was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T02:28:14.564Z

### AI review details

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

- **Mechanism:** The postinstall command invokes Playwright’s Chromium installer. Fetch functions request documentation and process the returned text.

- **Rationale:** Source inspection found a normal Playwright browser install hook and user-invoked documentation retrieval. The flagged network and Git behavior is consistent with the package’s knowledge ingestion functionality, with no concrete attack behavior established.

- **Files touched:** package.json, dist/git-fetcher.js, dist/context7-fetcher.js, dist/fetcher.js, dist/index.js

- **Network endpoints:** https://context7.com, https://github.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 89.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall hook runs Playwright’s Chromium installer., GitHub fetching clones a requested repository into a caller-provided temporary directory when invoked., Context7 fetching is limited to predefined topics and contacts the Context7 service., The public entrypoint exports the documentation fetchers; general HTML fetching accepts a caller-provided URL.

- **Evidence against:** Inspected code contains no credential or environment harvesting, arbitrary shell execution, or install-time consumer project mutation., The network operations retrieve documentation and are activated through exported fetch functions.
