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. 10 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:** 1.25.46 - **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 package has no install scripts, and its entry point only exports plugin functions. Runtime instrumentation is activated when Vite configures the plugin and connects to a bridge that defaults to loopback, consistent with the package's stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T09:54:13.577Z - **Finished:** 2026-11-01T09:54:37.137Z - **Download time:** 508 ms - **Static scan time:** 58 ms - **AI review time:** 22993 ms - **Total time:** 23560 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; this is a Vite instrumentation plugin that sends development runtime events to its local bridge. - **Trigger:** The application imports and configures the plugin in Vite; it is enabled by default for serve mode. - **Impact:** The bridge receives app runtime and build diagnostics for LensMCP observability; no unrelated collector or malicious behavior was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T09:54:37.137Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin injects a browser client and starts a WebSocket bridge on the configured host and port, defaulting to loopback. - **Rationale:** The package has no install scripts, and its entry point only exports plugin functions. Runtime instrumentation is activated when Vite configures the plugin and connects to a bridge that defaults to loopback, consistent with the package's stated purpose. - **Network endpoints:** 127.0.0.1 (default bridge host) ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Package metadata exposes index.js and lists dependencies but defines no install lifecycle scripts., The entry point exports the Vite plugin and event handler; it does not invoke them on import., The plugin applies to Vite serve mode by default, starts its bridge during configureServer, and gates build use behind an option or environment variable., The bridge defaults to 127.0.0.1 and listens on the configured host and port. - **Evidence against:** When enabled in Vite, the plugin instruments application code and sends runtime events through a browser client; this is consistent with its stated observability purpose. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.46. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.46 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 z=Object.defineProperty;var g=(e,n)=>z(e,"name",{value:n,configurable:!0});var Z=Object.defineProperty,d=g((e,n)=>Z(e,"name",{value:n,configurable:!0}),"c");import...

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: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** lib/plugin.js - **Public source:** [View source]() Source fingerprint signature matches a known malicious package signature; route for source-aware review.
