## 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:** 2.91.0
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The scanner's remote-execution signal is explained by a transparent, pinned pdf.js loader for a user-facing PDF feature. The package has no registry-install lifecycle hook or concrete malicious behavior in the inspected sources.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-09-15T22:55:50.904Z

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 confirmed malicious attack surface. The remote module load is a pinned PDF rendering dependency activated by the Assistant Chat feature.

- **Trigger:** A consumer renders Assistant Chat and opens a PDF thumbnail.

- **Impact:** It downloads third-party browser code for PDF rendering; no unconsented local mutation or exfiltration was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-15T22:57:31.009Z

### AI review details

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

- **Mechanism:** Dynamic import of pinned pdf.js rendering code.

- **Rationale:** The scanner's remote-execution signal is explained by a transparent, pinned pdf.js loader for a user-facing PDF feature. The package has no registry-install lifecycle hook or concrete malicious behavior in the inspected sources.

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The Assistant Chat feature dynamically imports a pinned pdf.js module from jsDelivr at runtime., The browser bundle contains Feathery API configuration and bundled authentication-provider code., The CommonJS entry only loads the package runtime bundle.

- **Evidence against:** There is no preinstall, install, or postinstall lifecycle hook., The remote import is confined to PDF thumbnail support and explicitly sets the matching PDF worker., No source evidence showed credential harvesting, shell execution, project-file mutation, persistence, or data exfiltration.

## Affected versions and remediation
