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. 9 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:** 1.23.1 - **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 is consistent with the package's Vite instrumentation purpose, and its client connects to the configured bridge host, defaulting to loopback. The manifest has no lifecycle scripts, and the inspected source establishes no malicious attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-09T10:45:00.358Z - **Finished:** 2026-10-09T10:45:44.557Z - **Download time:** 768 ms - **Static scan time:** 42 ms - **AI review time:** 43387 ms - **Total time:** 44199 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 source implements a Vite instrumentation plugin that sends browser events to its configured WebSocket host. - **Trigger:** Import and enable the plugin in a Vite project; client injection is enabled by default. - **Impact:** This supports the package's instrumentation function; inspected source does not establish credential theft, unrelated data exfiltration, or install-time mutation. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:45:44.557Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin starts its bridge during Vite server setup and injects a browser client that connects to the configured host and port. - **Rationale:** The flagged runtime bridge is consistent with the package's Vite instrumentation purpose, and its client connects to the configured bridge host, defaulting to loopback. The manifest has no lifecycle scripts, and the inspected source establishes no malicious attack behavior. - **Network endpoints:** ws://${e.host}:${e.port} ### 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 declares the package entrypoints and lists matching LensMCP instrumentation dependencies., The repository metadata identifies this as the LensMCP Vite plugin., The plugin defaults its WebSocket host to loopback and activates as a Vite plugin., The injected browser client connects to the host and port supplied to the plugin. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.23.1. - Review the evidence and your use of @lensmcp/vite-plugin@1.23.1 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 U=Object.defineProperty;var g=(e,n)=>U(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 Dependency Evidence - **Category:** Dependency - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() The manifest declares the package entrypoints and lists matching LensMCP instrumentation dependencies.
