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. 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:** 1.21.3 - **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. Static inspection shows a Vite development-observability plugin with loopback-default WebSocket telemetry and no install-time execution or malicious behavior. The scanner's network signal reflects this declared runtime bridge rather than a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-01T15:47:10.571Z - **Finished:** 2026-09-01T15:47:47.668Z - **Download time:** 502 ms - **Static scan time:** 48 ms - **AI review time:** 36546 ms - **Total time:** 37097 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 confirmed malicious attack surface. The package adds development telemetry only when its Vite plugin is configured and run. - **Trigger:** A consumer enables the exported Vite plugin during development. - **Impact:** It can expose browser development telemetry to the configured local LensMCP bridge, but no exfiltration or persistence is established. - **Review source:** ai\_review - **Reviewed:** 2026-09-01T15:47:47.668Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Injects local WebSocket telemetry and optional source instrumentation. - **Rationale:** Static inspection shows a Vite development-observability plugin with loopback-default WebSocket telemetry and no install-time execution or malicious behavior. The scanner's network signal reflects this declared runtime bridge rather than a concrete attack. ### 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 declares module entrypoints and LensMCP dependencies, with no install lifecycle script., The Vite plugin injects a browser runtime that records development telemetry, including console and fetch metadata., That runtime opens its bridge WebSocket to the configured host, which defaults to loopback. - **Evidence against:** No lifecycle hook, shell execution, file write, credential harvesting, or external endpoint is present in the inspected source., The observed instrumentation is activated through the exported Vite plugin and is consistent with its development-observability role. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.21.3. - Review the evidence and your use of @lensmcp/vite-plugin@1.21.3 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: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 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 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: (() => { ``` ### 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. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 93.0% - **Path:** package.json - **Public source:** [View source]() The manifest declares module entrypoints and LensMCP dependencies, with no install lifecycle script. Public source snippet (untrusted): ```json { "name": "@lensmcp/vite-plugin", "version": "1.21.3", "type": "module", "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": { ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The Vite plugin injects a browser runtime that records development telemetry, including console and fetch metadata. 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 ``` ### 8. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** lib/plugin.js - **Public source:** [View source]() That runtime opens its bridge WebSocket to the configured host, which defaults to loopback. Public source snippet (untrusted): ```javascript const WS_URL = 'ws://${e.host}:${e.port}'; let ws = null; let queue = []; let openOnce = false; ``` ## 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 1.21.3 (Dependency) - @lensmcp/core 1.21.3 (Dependency) - @lensmcp/protocol-types 1.21.3 (Dependency) - @lensmcp/react-instrumentation 1.21.3 (Dependency) - @lensmcp/valtio-instrumentation 1.21.3 (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:** 1.21.3 - **License:** Apache-2.0 - **Version published:** 2026-08-31T16:12:23.643Z - **Package first seen:** 2026-07-05T12:34:10.721Z - **Package last seen:** 2026-11-04T23:22:53.085Z - **Known versions:** 88 - **Latest version:** 1.25.60 - **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:** 42,299 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
