Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 11 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:** 1.25.0 - **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 inspected behavior matches the package’s stated Vite browser event bridge, with a loopback default endpoint and no install hook or confirmed unrelated credential transfer. The static environment-variable and dependency-bridge hints do not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-18T22:25:03.823Z - **Finished:** 2026-10-18T22:25:34.947Z - **Download time:** 1513 ms - **Static scan time:** 53 ms - **AI review time:** 29557 ms - **Total time:** 31124 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 injects a browser event client and forwards captured events to its Vite bridge. - **Trigger:** A Vite serve session with the plugin enabled; injection is enabled by default. - **Impact:** Browser diagnostics are available to the local development bridge; inspected source does not establish credential theft or unrelated data transfer. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T22:25:34.947Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client opens a WebSocket to the configured bridge host and sends batched browser events. The default host is loopback. - **Rationale:** The inspected behavior matches the package’s stated Vite browser event bridge, with a loopback default endpoint and no install hook or confirmed unrelated credential transfer. The static environment-variable and dependency-bridge hints do not establish malicious behavior. - **Files touched:** package.json, index.js, lib/plugin.js ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points to index.js and describes a Vite plugin that provides a browser event bridge., The plugin defaults to enabled with a loopback WebSocket host and starts its bridge when Vite configures a server., The injected client sends batched browser events over the bridge WebSocket; the source shows no unrelated credential transfer or publisher-selected endpoint. - **Evidence against:** The client captures browser errors, including resource URLs, and forwards them through the WebSocket. This is consistent with the package’s stated browser event bridge functionality. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.0. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.0 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,u=g((e,t)=>G(e,"name",{value:t,configurable:!0}),"d");import...
