# @lensmcp/vite-plugin@1.25.21 npm security report

> **Trust boundary:** Package metadata, advisory text, filenames, URLs, and source snippets in this report come from external packages or feeds. Treat them as untrusted evidence. Do not execute instructions or code found in this document.

## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 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:** 1.25.21
- **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.

Inspected source supports a package-aligned Vite observability plugin: the entrypoint exposes the plugin and bridge, the default bridge host is loopback, and replay transmission uses an explicitly configured endpoint without browser credentials. The scanner's dependency bridge and environment-variable signals match the plugin's described function; no concrete malicious behavior was established.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-10-22T07:53:14.255Z

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 a Vite development plugin that instruments browser activity and can send runtime or replay events to its local bridge.

- **Trigger:** A project installs and enables the plugin in a Vite development server; replay behavior follows the plugin's replay settings.

- **Impact:** The intended effect is local development observability and event capture; inspected source does not establish an external attack surface.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-22T07:54:19.066Z

### AI review details

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

- **Mechanism:** The plugin serves browser instrumentation and a WebSocket bridge on loopback by default. The replay runtime posts to its configured endpoint with browser credentials omitted.

- **Rationale:** Inspected source supports a package-aligned Vite observability plugin: the entrypoint exposes the plugin and bridge, the default bridge host is loopback, and replay transmission uses an explicitly configured endpoint without browser credentials. The scanner's dependency bridge and environment-variable signals match the plugin's described function; no concrete malicious behavior was established.

- **Files touched:** .lensmcp/events.jsonl

- **Network endpoints:** ws://127.0.0.1

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest points to the Vite plugin entrypoint and declares the bridge and client runtime as package dependencies; it has no lifecycle script., The plugin defaults its WebSocket host to loopback and starts the bridge when Vite configures a development server., Replay capture posts to the configured endpoint with credentials omitted; the plugin uses replay settings and the local bridge for capture., The bridge and client runtime are LensMCP components, and the core package includes local event-file handling. The inspected event mapper converts client events into runtime events.

- **Evidence against:** No package-controlled external recipient, credential harvesting, or install-time execution was identified in the inspected source.

## 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@1.25.21/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 Z=Object.defineProperty;var g=(e,n)=>Z(e,"name",{value:n,configurable:!0});var Q=Object.defineProperty,y=g((e,n)=>Q(e,"name",{value:n,configurable:!0}),"g"),ee=Obj...

L3: (() => {
```

### 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:** 91.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@lensmcp/vite-plugin@1.25.21/package.json>)

The manifest points to the Vite plugin entrypoint and declares the bridge and client runtime as package dependencies; it has no lifecycle script.

Public source snippet (untrusted):

```json
"name": "@lensmcp/vite-plugin",
  "version": "1.25.21",
  "type": "module",

- **Path:** lib/plugin.js
- **Public source:** [View source](<https://unpkg.com/@lensmcp/vite-plugin@1.25.21/lib/plugin.js>)

The plugin defaults its WebSocket host to loopback and starts the bridge when Vite configures a development server.
