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. 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:** 1.24.1 - **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 entrypoint, dependencies, and inspected plugin behavior align with a Vite observability plugin. The static bridge and environment-variable signals reflect that functionality; the inspected evidence does not establish an attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-11T11:53:33.858Z - **Finished:** 2026-10-11T11:54:04.306Z - **Download time:** 252 ms - **Static scan time:** 40 ms - **AI review time:** 30155 ms - **Total time:** 30448 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 attack was identified. The inspected code implements a Vite development plugin and browser event bridge consistent with the package metadata. - **Trigger:** A consumer imports and enables the Vite plugin; browser instrumentation is injected when enabled. - **Impact:** No malicious impact was established from the inspected source; the observed collection and transport serve the stated observability feature. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T11:54:04.306Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin starts a WebSocket bridge, defaults its host to the loopback address, and injects browser code that batches events for that connection. - **Rationale:** The entrypoint, dependencies, and inspected plugin behavior align with a Vite observability plugin. The static bridge and environment-variable signals reflect that functionality; the inspected evidence does not establish an attack. - **Network endpoints:** 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:** package.json exposes the Vite plugin through index.js and lists matching LensMCP bridge and instrumentation dependencies., The plugin runs as Vite middleware, defaults its WebSocket host to 127.0.0.1, and gates build use behind an option or environment variable., The generated browser client batches events for its WebSocket connection; this matches the package’s stated browser event bridge purpose. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.24.1. - Review the evidence and your use of @lensmcp/vite-plugin@1.24.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## 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]() 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 V=Object.defineProperty;var g=(e,t)=>V(e,"name",{value:t,configurable:!0});var $=Object.defineProperty,d=g((e,t)=>$(e,"name",{value:t,configurable:!0}),"c");import... 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 Dependency Evidence - **Category:** Dependency - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() package.json exposes the Vite plugin through index.js and lists matching LensMCP bridge and instrumentation dependencies. Public source snippet (untrusted): ```json "main": "./index.js", "module": "./index.js", "types": "./index.d.ts", "exports": { "./package.json": "./package.json", ".": { "types": "./index.d.ts", "import": "./index.js", "default": "./index.js" } }, "dependencies": { "@babel/cor ``` ### 6. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() package.json exposes the Vite plugin through index.js and lists matching LensMCP bridge and instrumentation dependencies. Public source snippet (untrusted): ```json "dependencies": { "@babel/core": "^7.0.0", "@lensmcp/bridge": "1.24.1", "@lensmcp/core": "1.24.1", "@lensmcp/protocol-types": "1.24.1", "@lensmcp/react-instrumentation": "1.24.1", "@lensmcp/valtio-instrumentation": "1.24.1", "tslib": "^2.3.0" }, "peerDependencies": { "vite": "^5.0.0 || ^6.0.0 || ^7.0.0 || ^8.0.0" }, ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin runs as Vite middleware, defaults its WebSocket host to 127.0.0.1, and gates build use behind an option or environment variable. Public source snippet (untrusted): ```javascript },t={}){const s=e.enabled??!0,p=e.wsHost??"127.0.0.1",i=e.injectClient??!0;let f,u,r;const a=L(t),y=e.aliasValtio??!0,_=e.transformSource??!0,w=e.applyOnBuild??process.env.LENSMCP_VITE_APPLY_ON_BUILD==="1";return{name:"@lensmcp/vite-plugin",apply:d((n,l)=>s&&(l.command==="serve"||w),"apply"),enforce:"pre",wsPort:d(()=>f,"wsPort"),config(){if(!(!s||!y))return{resolve:{alias:[{find:/^valtio$/,replacement:"@lensmcp/valtio-instrumentation"}]}}},async configureServer(n){if(!s)return;r=J(24).toString("base64url"),u=await Z({host:p,port:e.wsPort??0,bus:t.bus,se ``` ### 8. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The generated browser client batches events for its WebSocket connection; this matches the package’s stated browser event bridge purpose. Public source snippet (untrusted): ```javascript abId = TAB_ID; batch.push(env); if (!flushScheduled) { flushScheduled = true; setTimeout(flushBatch, 0); } } // The tab may die with a flush pending \u2014 drain synchronously so nothing is lost. window.addEventListener('pagehide', flushBatch); function open() { try { w ``` ### 9.
