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 inspected collection and transport implement the package's stated browser event bridge, with a localhost default and Vite-driven activation. No concrete malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T10:44:37.281Z - **Finished:** 2026-10-09T10:45:15.174Z - **Download time:** 1040 ms - **Static scan time:** 25 ms - **AI review time:** 36827 ms - **Total time:** 37893 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 Vite plugin injects a browser observability bridge that sends telemetry to its configured WebSocket, defaulting to localhost. - **Trigger:** A user enables and runs the plugin through Vite; browser instrumentation runs on the served application. - **Impact:** Telemetry may include values logged by the application and requested URLs; the inspected code showed no credential harvesting or unrelated destination. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:45:15.174Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bridge collects application events, including console output and fetch metadata, then sends them through the WebSocket. - **Rationale:** The inspected collection and transport implement the package's stated browser event bridge, with a localhost default and Vite-driven activation. No concrete malicious behavior was found. - **Files touched:** package.json, lib/plugin.js - **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 package describes itself as a Vite plugin with a browser event bridge., The plugin defaults its WebSocket host to localhost and starts its bridge from Vite's server configuration., The browser runtime sends collected events over that WebSocket., It reports console arguments and fetch method, URL, and response status as telemetry. - **Evidence against:** The inspected telemetry matches the package's stated observability purpose; no credential forwarding or unrelated attack behavior was identified. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.21.2. - Review the evidence and your use of @lensmcp/vite-plugin@1.21.2 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. 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 N=Object.defineProperty;var d=(e,t)=>N(e,"name",{value:t,configurable:!0});var x=Object.defineProperty,u=d((e,t)=>x(e,"name",{value:t,configurable:!0}),"c");import... L2: (() => { ``` ### 2. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 3. 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. ### 4. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() The package describes itself as a Vite plugin with a browser event bridge. Public source snippet (untrusted): ```json "description": "LensMCP Vite plugin — valtio alias, source transform, and browser event bridge.", "keywords" ``` ### 5. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin defaults its WebSocket host to localhost and starts its bridge from Vite's server configuration. Public source snippet (untrusted): ```javascript const s=e.enabled??!0,f=e.wsHost??"127.0.0.1",i=e.injectClient??!0;let v,g;const b=E(t),D=e.aliasValtio??!0,B=e.transformSource??!0;return{name:"@lensmcp/vite-plugin",apply:s?void 0:()=>!1,enfor ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin defaults its WebSocket host to localhost and starts its bridge from Vite's server configuration. Public source snippet (untrusted): ```javascript g=await j({host:f,port:e.wsPort??0,bus:t.bus,sessionId:t.sessionId}),v=g.port,r.ws.on("vite:error",n=>{b(O(n,t.sessionId))});let a=0,o=0,l=0;const p=[],m=u((n,h)=>{a=Date.now(),o+=1 ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The browser runtime sends collected events over that WebSocket. Public source snippet (untrusted): ```javascript 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 */ } } ``` ### 8. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() It reports console arguments and fetch method, URL, and response status as telemetry. Public source snippet (untrusted): ```javascript 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-fetch (@lensmcp/react-instrumentation) wra ``` ### 9. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() It reports console arguments and fetch method, URL, and response status as telemetry. 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)) }); } c ``` ### 10.
