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:** 1.24.3 - **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. Source inspection supports ordinary Vite observability behavior: the manifest uses version-matched LensMCP bridge and instrumentation dependencies, and the runtime sends event batches to the configured bridge. No malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-12T12:42:40.363Z - **Finished:** 2026-10-12T12:43:11.495Z - **Download time:** 759 ms - **Static scan time:** 50 ms - **AI review time:** 30322 ms - **Total time:** 31132 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 plugin starts a local development bridge and injects a browser client that forwards observability events to it. - **Trigger:** Using the plugin in a Vite development server; the client connects when the injected runtime loads in a browser. - **Impact:** The observed behavior supports the package's stated Vite observability purpose; no confirmed unrelated data recipient or malicious action was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T12:43:11.495Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin configures a bridge using its configured host, port, and token, then the injected client sends queued event batches over that WebSocket. - **Rationale:** Source inspection supports ordinary Vite observability behavior: the manifest uses version-matched LensMCP bridge and instrumentation dependencies, and the runtime sends event batches to the configured bridge. No malicious behavior was established. - **Files touched:** package.json, lib/plugin.js ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points to an entrypoint with version-matched LensMCP bridge and instrumentation dependencies, consistent with a Vite observability plugin., The plugin activates during Vite serve by default and builds a browser WebSocket URL from its configured host, server port, and token., The injected browser runtime sends queued event batches to that WebSocket; the inspected code shows no unrelated external recipient or credential collection. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.24.3. - Review the evidence and your use of @lensmcp/vite-plugin@1.24.3 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 $=Object.defineProperty;var g=(e,t)=>$(e,"name",{value:t,configurable:!0});var G=Object.defineProperty,h=g((e,t)=>G(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. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 86.0% - **Path:** package.json - **Public source:** [View source]() The manifest points to an entrypoint with version-matched LensMCP bridge and instrumentation dependencies, consistent with a Vite observability plugin. Public source snippet (untrusted): ```json "dependencies": { "@babel/core": "^7.0.0", "@lensmcp/bridge": "1.24.3", "@lensmcp/core": "1.24.3", "@lensmcp/protocol-types": "1.24.3", "@lensmcp/react-instrumentation": "1.24.3", "@lensmcp/valtio-instrumentation": "1.24.3", "tslib": "^2.3.0" }, ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 86.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin activates during Vite serve by default and builds a browser WebSocket URL from its configured host, server port, and token. Public source snippet (untrusted): ```javascript process.env.LENSMCP_VITE_APPLY_ON_BUILD==="1";return{name:"@lensmcp/vite-plugin",apply:h((n,a)=>r&&(a.command==="serve"||w),"apply"),enforce:"pre",wsPort:h(()=>f,"wsPort"),config(n){if(!r)return;const a=checkoutViteCacheDir(n?.root,n?.cacheDir);a&&console.log(`[lensmcp] node_modules is shared with another checkout \u2014 Vite's dependency cache moves to ${a}`);const o=process.env.LENSMCP_FREEZE==="1";o&&console.log("[lensmcp] frozen worktree inst ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 86.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The injected browser runtime sends queued event batches to that WebSocket; the inspected code shows no unrelated external recipient or credential collection.
