Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 8 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:** 1.23.13 - **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 flagged runtime bridge connects to matching first-party LensMCP components, while the source shows Vite instrumentation over a loopback-default WebSocket. No concrete malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-09T10:45:13.386Z - **Finished:** 2026-10-09T10:45:41.277Z - **Download time:** 1031 ms - **Static scan time:** 40 ms - **AI review time:** 26819 ms - **Total time:** 27891 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 malicious attack surface was identified. The package runs as a Vite plugin and reports browser and build instrumentation to its associated bridge. - **Trigger:** A consumer configures the plugin in a Vite project; browser reporting is activated when the injected client runs. - **Impact:** The inspected behavior supports local development observability; no credential harvesting, unrelated remote endpoint, or install-time mutation was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:45:41.277Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin starts a WebSocket bridge and the browser client sends instrumentation events to it. The host defaults to loopback, and build use requires explicit configuration. - **Rationale:** The flagged runtime bridge connects to matching first-party LensMCP components, while the source shows Vite instrumentation over a loopback-default WebSocket. No concrete malicious behavior was identified. - **Files touched:** package.json, lib/plugin.js - **Network endpoints:** ws://127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest has no install lifecycle scripts and depends on matching @lensmcp bridge and instrumentation packages., The plugin is enabled by default for Vite serve and defaults its WebSocket host to loopback; build application requires explicit configuration., The browser runtime sends instrumentation and page events over the plugin WebSocket, consistent with the package’s Vite observability purpose. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.23.13. - Review the evidence and your use of @lensmcp/vite-plugin@1.23.13 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 W=Object.defineProperty;var g=(e,n)=>W(e,"name",{value:n,configurable:!0});var V=Object.defineProperty,u=g((e,n)=>V(e,"name",{value:n,configurable:!0}),"d");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 Lifecycle Evidence - **Category:** Manifest - **Confidence:** 93.0% - **Path:** package.json - **Public source:** [View source]() The manifest has no install lifecycle scripts and depends on matching @lensmcp bridge and instrumentation packages. Public source snippet (untrusted): ```json "dependencies": { "@babel/core": "^7.0.0", "@lensmcp/bridge": "1.23.13", "@lensmcp/core": "1.23.13", "@lensmcp/protocol-types": "1.23.13", "@lensmcp/react-instrumentation": "1.23.13", "@lensmcp/valtio-instrumentati ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin is enabled by default for Vite serve and defaults its WebSocket host to loopback; build application requires explicit configuration. Public source snippet (untrusted): ```javascript nsmcpVitePlugin(e={},n={}){const s=e.enabled??!0,p=e.wsHost??"127.0.0.1",i=e.injectClient??!0;let f,h;const r=O(n),d=e.aliasValtio??!0,v=e.transformSource??!0,S=e.applyOnBuild??process.env.LENSMCP_VITE_APPLY_ON_BUILD==="1";return{name:"@lensmcp/vite-plugin",apply:u((t,c)=>s&&(c.command==="serve"||S) ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The browser runtime sends instrumentation and page events over the plugin WebSocket, consistent with the package’s Vite observability purpose. Public source snippet (untrusted): ```javascript env.at = Date.now(); env.tabId = 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 { ws = new WebSocket(WS_URL); } catch (e) { setTimeout(open, 1000); return; } ws.addEventListe ``` ### 8. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The browser runtime sends instrumentation and page events over the plugin WebSocket, consistent with the package’s Vite observability purpose. Public source snippet (untrusted): ```javascript @lensmcp/react-instrumentation, // @lensmcp/valtio-instrumentation).
