## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 9 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:** 1.25.1
- **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 manifest has no install lifecycle hooks, and the runtime is activated through Vite plugin configuration. Its inspected event transfer supports the package’s stated observability function and defaults to a local bridge; no concrete attack behavior was found.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 96.0%

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 package provides opt-in Vite development observability through a local WebSocket bridge.

- **Trigger:** A consumer adds the plugin to Vite configuration and starts the development server; build instrumentation requires explicit opt-in.

- **Impact:** Events are available to the local LensMCP bridge; inspected source does not establish unauthorized collection or transfer.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-19T09:50:26.431Z

### AI review details

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

- **Mechanism:** The plugin injects a browser client that sends observability events, including fetch metadata, to the bridge. The default host is loopback, though the consumer can configure it.

- **Rationale:** The manifest has no install lifecycle hooks, and the runtime is activated through Vite plugin configuration. Its inspected event transfer supports the package’s stated observability function and defaults to a local bridge; no concrete attack behavior was found.

- **Network endpoints:** 127.0.0.1

### Review decision

- **Verdict:** Clean

- **Confidence:** 96.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest identifies the package, exports its Vite entrypoint, and lists matching LensMCP dependencies; it contains no lifecycle scripts., The plugin defaults its WebSocket host to loopback and runs on Vite serve, with builds requiring an explicit opt-in., When enabled, it starts a bridge on the configured host and port, using a generated token., The injected client connects to that bridge, and its fetch instrumentation reports request metadata as observability events.

## Affected versions and remediation

This report applies to @lensmcp/vite-plugin@1.25.1.

## Public findings

### 1. Medium: Environment Vars
- **Category:** Source
- **Confidence:** 75.0%

Package source references environment variables.

### 2. High: Copied Package Dependency Bridge
- **Category:** Source
- **Confidence:** 83.0%
- **Path:** lib/plugin.js
- **Public source:** [View source](<https://unpkg.com/@lensmcp/vite-plugin@1.25.1/lib/plugin.js>)

Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.

Public source snippet (untrusted):

```javascript
package = @lensmcp/vite-plugin; repositoryIdentity = lensmcp; dependency = @babel/core
L1: "use strict";var G=Object.defineProperty;var g=(e,t)=>G(e,"name",{value:t,configurable:!0});var J=Object.defineProperty,w=g((e,t)=>J(e,"name",{value:t,configurable:!0}),"g"),q=Obje...
L2: (() => {
```

### 3. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 4. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 75.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 5. Low: Suspicious Lifecycle Evidence
- **Category:** Manifest
- **Confidence:** 96.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@lensmcp/vite-plugin@1.25.1/package.json>)

The manifest identifies the package, exports its Vite entrypoint, and lists matching LensMCP dependencies; it contains no lifecycle scripts.
