## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 10 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 1.25.43
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The package’s observability purpose explains browser event collection, but its default session replay can capture unmasked form values, including password fields. The inspected code sends recordings to the local bridge and does not show an unrelated external collector, so this warrants a warning rather than a publish block.

## 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:** Default session replay can capture page content and unmasked form values and send recordings to the LensMCP bridge.

- **Trigger:** A developer starts a Vite dev server with the plugin enabled; replay is enabled by default unless its setting disables it.

- **Impact:** Sensitive text entered into page forms may be included in recordings and made available to the local LensMCP consumer.

- **Evidence paths:** lib/plugin.js, lib/replay-setting.js, lib/types.d.ts, .lpm-dependency-evidence-9c654c37-3693-4806-9121-1dccf77a1c8d/1/npm-linux/lib/replay/types.js, .lpm-dependency-evidence-9c654c37-3693-4806-9121-1dccf77a1c8d/1/npm-linux/replay-source.js

### AI review details

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

- **Mechanism:** The plugin injects an rrweb recorder into served pages, which streams recordings to the bridge over HTTP using the configured host and port.

- **Rationale:** The package’s observability purpose explains browser event collection, but its default session replay can capture unmasked form values, including password fields. The inspected code sends recordings to the local bridge and does not show an unrelated external collector, so this warrants a warning rather than a publish block.

- **Network endpoints:** ws://127.0.0.1:\<ephemeral-port\>/?\<token\>, http://127.0.0.1:\<ephemeral-port\>/replay, http://127.0.0.1:\<ephemeral-port\>/replay/blob

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The plugin injects the replay recorder into served pages when replay is enabled; its type documentation says session replay is on by default., When no replay option or environment override is set, replayEnabled falls back to the capture settings file and returns enabled if reading or parsing it fails., Replay defaults to maskAllInputs false, and the recorder sets password masking to false when maskAllInputs is off.

- **Evidence against:** The package has no lifecycle scripts; replay runs when the user adds the plugin to a Vite app., The README describes the plugin as an observability tool that streams browser events over a local WebSocket., The default bridge host is 127.0.0.1, and the served runtime includes a per-start token.

## 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@1.25.43/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 Z=Object.defineProperty,d=g((e,n)=>Z(e,"name",{value:n,configurable:!0}),"c");import...
L2: `);if(t!==B)return null;const u=f??e.wsPort??0,r=process.env.LENSMCP_APP||process.env.NX_TASK_TARGET_PROJECT;return buildInlineClientRuntime({host:p,port:u,token:o,hmrRecovery:e.hm...
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. High: Known Malware Source Fingerprint Signature
- **Category:** Supply Chain
- **Confidence:** 94.0%
- **Path:** lib/plugin.js
- **Public source:** [View source](<https://unpkg.com/@lensmcp/vite-plugin@1.25.43/lib/plugin.js>)

Source fingerprint signature matches a known malicious package signature; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = malicious_source_fingerprint_signature
signature = 118688338f0ed54a
signatureType = suspicious_hashes
sourceLabel = final_verdict:malicious
matchedPackage = @lensmcp/vite-plugin@1.25.41
matchedPath = lib/plugin.js
matchedIdentity = npm:QGxlbnNtY3Avdml0ZS1wbHVnaW4:1.25.41
similarity = 1.000
shingleOverlap = 5
summary = package final verdict is malicious

### 6. Medium: Ai Review Evidence

- **Path:** lib/types.d.ts
- **Public source:** [View source](<https://unpkg.com/@lensmcp/vite-plugin@1.25.43/lib/types.d.ts>)

The plugin injects the replay recorder into served pages when replay is enabled; its type documentation says session replay is on by default.

Public source snippet (untrusted):

```typescript
* Session replay: the page records itself with rrweb (`/@lensmcp/replay`, injected after the runtime) and streams
     * the recording to the bridge (planning/replay/00-plan.md). On by default; `LENSMCP_REPLAY=0` in the dev server's
     * env wins over t
```

### 7. Medium: Ai Review Evidence

- **Public source:** [View source](<https://unpkg.com/@lensmcp/vite-plugin@1.25.43/lib/plugin.js>)

The plugin injects the replay recorder into served pages when replay is enabled; its type documentation says session replay is on by default.

Public source snippet (untrusted):

```javascript

```

### 8. Medium: Ai Review Evidence

- **Path:** lib/replay-setting.js
- **Public source:** [View source](<https://unpkg.com/@lensmcp/vite-plugin@1.25.43/lib/replay-setting.js>)

When no replay option or environment override is set, replayEnabled falls back to the capture settings file and returns enabled if reading or parsing it fails.

Public source snippet (untrusted):

```javascript
rom"@lensmcp/core/lens-events";export function replayEnabled(r){const e=(r.env??process.env).LENSMCP_REPLAY?.trim().toLowerCase();if(e==="0"||e==="off"||e==="false")return!1;if(e==="1"||e==="on"||e==="true")return!0;if(r.option!==void 0)return r.option;try{return JSON.p
