## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 16 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:** 2.99.1
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The inspected package is a React SDK with conventional entrypoints and package-aligned browser networking. Its dynamic PDF.js import is tied to a fixed, version-pinned CDN dependency, while sensitive link headers are origin-gated.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-09-29T00:35:02.449Z
- **Finished:** 2026-09-29T00:37:03.152Z
- **Download time:** 1775 ms
- **Static scan time:** 26327 ms
- **AI review time:** 92600 ms
- **Total time:** 120703 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 malicious attack surface was identified in the inspected entry bundles. The observed network behavior supports application APIs and a fixed PDF.js asset dependency.

- **Trigger:** Importing and using the React package can initialize its application components; PDF rendering activates the fixed PDF.js loader.

- **Impact:** No confirmed credential theft, arbitrary remote endpoint selection, install-time attack, persistence, or destructive behavior was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-29T00:37:03.152Z

### AI review details

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

- **Mechanism:** The bundles use normal module imports, backend-origin-gated request headers, and a version-pinned PDF.js CDN path.

- **Rationale:** The inspected package is a React SDK with conventional entrypoints and package-aligned browser networking. Its dynamic PDF.js import is tied to a fixed, version-pinned CDN dependency, while sensitive link headers are origin-gated.

- **Network endpoints:** https://cdn.jsdelivr.net/npm/pdfjs-dist@5.4.296

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package declares standard CommonJS and ES module entrypoints., The assistant bundle constructs fixed PDF.js module and worker paths., Request headers are sent only when the destination matches configured backend origins., The UMD file is a bundled module that registers a default export., The smaller CommonJS bundle imports local components and React.

- **Evidence against:** The assistant bundle contains a dynamic import mechanism for its PDF.js CDN dependency.
