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. Source inspection found a user-invoked local development telemetry bridge, not concrete malware. Because it injects broad browser instrumentation and the required clean decision is unavailable under incomplete analysis coverage, downgrade to warn. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 62.0% - **Started:** 2026-09-12T17:24:02.929Z - **Finished:** 2026-09-12T17:25:42.165Z - **Download time:** 770 ms - **Static scan time:** 28 ms - **AI review time:** 98437 ms - **Total time:** 99236 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:** When enabled in a Vite development server, the package injects browser instrumentation that observes console activity and fetch URLs. It forwards collected events to a local WebSocket bridge. - **Trigger:** A project configures and runs the Vite plugin. - **Impact:** Development-page console content and request metadata can be exposed to the local bridge process. - **Evidence paths:** lib/plugin.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T17:25:42.165Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Injected browser telemetry sent to a loopback WebSocket bridge. - **Rationale:** Source inspection found a user-invoked local development telemetry bridge, not concrete malware. Because it injects broad browser instrumentation and the required clean decision is unavailable under incomplete analysis coverage, downgrade to warn. - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 62.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** High - **Evidence for warning:** The plugin injects a browser module into Vite pages., The injected module sends batched events over a WebSocket., It intercepts console calls and fetch metadata, including requested URLs. - **Evidence against:** The manifest has no preinstall, install, postinstall, or bin entry., The default WebSocket host is loopback, and no external endpoint or credential harvesting was found., No shell execution, file writes, destructive action, or persistence was found. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.22.1. - Review the evidence and your use of @lensmcp/vite-plugin@1.22.1 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 p=(e,t)=>V(e,"name",{value:t,configurable:!0});var $=Object.defineProperty,d=p((e,t)=>$(e,"name",{value:t,configurable:!0}),"u");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. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** package.json - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```json stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 1 ``` ### 6. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 62.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin injects a browser module into Vite pages. Public source snippet (untrusted): ```javascript transformIndexHtml(){if(!(!a||!o))return[{tag:"script",attrs:{type:"module",src:D},injectTo:"head-prepend"}]} ``` ### 7. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 62.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The injected module sends batched events over a WebSocket. Public source snippet (untrusted): ```javascript function flushBatch() { flushScheduled = false; if (!batch.length) return; const events = batch; batch = []; if (ws && ws.readyState === 1) { try { ws.send(JSON.stringify(events.length === 1 ? events[0] : { kind: 'batch', at: Date.now(), tabId: TAB_ID, events })); return; } catch (e) { /* fall through to queue */ } } for (const ev of events) queue.push(ev); } ``` ### 8. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 62.0% - **Path:** lib/plugin.js - **Public source:** [View source]() It intercepts console calls and fetch metadata, including requested URLs. Public source snippet (untrusted): ```javascript for (const level of ['log','info','warn','error','debug']) { const original = console[level]; console[level] = function(...args) { try { send({ kind: 'console', level, args: args.map((a) => safe(a)) }); } catch {} return original.apply(this, args); }; } // fetch const origFetch = window.fetch.bind(window); window.fetch = async function(input, init) { const method = (init && init.method) || (input && input.method) || 'GET'; const url = typeof input === 'string' ? input : (input && (input.url || String(input))); const start = Date.now(); // flow ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 7 - **Optional dependencies:** 0 - **Peer dependencies:** 1 - **Development dependencies:** 0 - **Published dependency-graph edges:** 8 ### Published dependency entries - @babel/core ^7.0.0 (Dependency) - @lensmcp/bridge 1.22.1 (Dependency) - @lensmcp/core 1.22.1 (Dependency) - @lensmcp/protocol-types 1.22.1 (Dependency) - @lensmcp/react-instrumentation 1.22.1 (Dependency) - @lensmcp/valtio-instrumentation 1.22.1 (Dependency) - tslib ^2.3.0 (Dependency) - vite ^5.0.0 || ^6.0.0 || ^7.0.0 || ^8.0.0 (PeerDependency) ## Package metadata - **Package:** @lensmcp/vite-plugin - **Ecosystem:** npm - **Version:** 1.22.1 - **License:** Apache-2.0 - **Version published:** 2026-09-10T06:51:58.631Z - **Package first seen:** 2026-07-05T12:34:10.721Z - **Package last seen:** 2026-11-04T20:00:29.329Z - **Known versions:** 87 - **Latest version:** 1.25.58 - **Appeal under review:** No - **Description:** LensMCP Vite plugin — valtio alias, source transform, and browser event bridge. - **Maintainers:** davidmantoon - **Keywords:** lensmcp, mcp, observability, ai-agents, claude, vite, vite-plugin - **Runtime engines:** node: \>=18 - **Artifact files:** 11 - **Artifact unpacked size:** 49,917 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
