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:** 1.23.3 - **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. The inspected entrypoint and plugin code implement Vite instrumentation using same-scope bridge dependencies, with no install hook or concrete malicious behavior found. The observed event reporting is consistent with the plugin’s stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-09T10:45:02.976Z - **Finished:** 2026-10-09T10:45:39.193Z - **Download time:** 1031 ms - **Static scan time:** 38 ms - **AI review time:** 35147 ms - **Total time:** 36217 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 Vite instrumentation and sends browser event metadata to a configurable local bridge. - **Trigger:** When the plugin is enabled during Vite serving and the injected browser client runs. - **Impact:** The inspected behavior supports the package’s instrumentation purpose; no concrete malicious behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:45:39.193Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client sends instrumentation events, including fetch metadata, over a WebSocket whose default host is loopback. - **Rationale:** The inspected entrypoint and plugin code implement Vite instrumentation using same-scope bridge dependencies, with no install hook or concrete malicious behavior found. The observed event reporting is consistent with the plugin’s stated purpose. - **Files touched:** package.json, lib/plugin.js - **Network endpoints:** ws://${e.host}:${e.port}, 127.0.0.1 (default host) ### 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 declares same-scope LensMCP bridge and instrumentation dependencies, with no lifecycle scripts., The plugin activates for Vite serving by default, and the browser client connects to a configurable WebSocket host that defaults to loopback., The client reports fetch metadata such as URL and status to that WebSocket for the plugin’s instrumentation function. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.23.3. - Review the evidence and your use of @lensmcp/vite-plugin@1.23.3 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 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 Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The manifest declares same-scope LensMCP bridge and instrumentation dependencies, with no lifecycle scripts. Public source snippet (untrusted): ```json "dependencies": { "@babel/core": "^7.0.0", "@lensmcp/bridge": "1.23.3", "@lensmcp/core": "1.23.3", "@lensmcp/protocol-types": "1.23.3", "@lensmcp/react-instrumentation" ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin activates for Vite serving by default, and the browser client connects to a configurable WebSocket host that defaults to loopback.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The client reports fetch metadata such as URL and status to that WebSocket for the plugin’s instrumentation function.
