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 shows a Vite development instrumentation plugin whose browser client reports diagnostics to a bridge, defaulting to loopback. No install-time execution, unrelated fixed recipient, or concrete malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-09T10:44:32.890Z - **Finished:** 2026-10-09T10:45:09.824Z - **Download time:** 754 ms - **Static scan time:** 35 ms - **AI review time:** 36144 ms - **Total time:** 36934 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 instruments browser activity and reports diagnostic events to its WebSocket bridge. - **Trigger:** A project enables and runs the plugin under Vite’s dev server. - **Impact:** Diagnostic data may include application console content and request URLs, but the inspected behavior is consistent with the plugin’s stated instrumentation role and does not establish an attack surface. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:45:09.824Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The browser client sends console events and fetch request metadata to the bridge; the default host is loopback. - **Rationale:** Source inspection shows a Vite development instrumentation plugin whose browser client reports diagnostics to a bridge, defaulting to loopback. No install-time execution, unrelated fixed recipient, or concrete malicious behavior was identified. - **Files touched:** package.json, lib/plugin.js - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exports a Vite plugin entry point and lists matching LensMCP instrumentation dependencies., The plugin defaults to enabled and uses 127.0.0.1 as its WebSocket host., The dev-server hook starts the bridge when the plugin is enabled., The injected browser client sends console events and fetch metadata through its WebSocket; this is consistent with the plugin’s instrumentation purpose. - **Evidence against:** The inspected manifest and entry point show no install lifecycle hook; runtime behavior is activated through the Vite plugin., The default WebSocket host is loopback; no unrelated fixed recipient or credential harvesting was identified in the inspected source. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.22.3. - Review the evidence and your use of @lensmcp/vite-plugin@1.22.3 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 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.

Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() The manifest exports a Vite plugin entry point and lists matching LensMCP instrumentation dependencies. Public source snippet (untrusted): ```json { "name": "@lensmcp/vite-plugin", "version": "1.22.3", "type": "module", "main": "./index.js", "module": "./index.js", "types": "./index.d.ts", "exports": { "./package.json": "./package.json", ".": { "types": "./index.d.ts", "import": " ``` ### 7. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() The manifest exports a Vite plugin entry point and lists matching LensMCP instrumentation dependencies.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin defaults to enabled and uses 127.0.0.1 as its WebSocket host. Public source snippet (untrusted): ```javascript const o=e.enabled??!0,m=e.wsHost??"127.0.0.1",a=e.injectClient??!0;let v,u;const g=L(t),l=e.aliasValtio??!0,b= ``` ### 9.
