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 user-invoked Vite instrumentation with matching LensMCP dependencies and a loopback WebSocket default. The reporting behavior fits the package function, and no concrete malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T10:44:37.777Z - **Finished:** 2026-10-09T10:45:14.300Z - **Download time:** 515 ms - **Static scan time:** 38 ms - **AI review time:** 35969 ms - **Total time:** 36523 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 package provides a Vite development observability plugin that reports browser events to its configured WebSocket bridge. - **Trigger:** A consuming project enables the plugin in Vite, normally while running the development server. - **Impact:** No confirmed attack surface was established; the inspected reporting behavior is consistent with the package's Vite observability function. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:45:14.300Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The injected browser client reports console and fetch metadata through the bridge; the configured host defaults to loopback. - **Rationale:** Source inspection shows user-invoked Vite instrumentation with matching LensMCP dependencies and a loopback WebSocket default. The reporting behavior fits the package function, and no concrete malicious behavior was identified. - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest identifies a Vite plugin with matching LensMCP runtime dependencies and no install lifecycle hook., The plugin activates through Vite and defaults its WebSocket host to loopback; its browser runtime reports console and fetch metadata for observability., Fetch reporting sends request URLs and status metadata, but inspected code shows no credential collection or unrelated network destination. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.22.5. - Review the evidence and your use of @lensmcp/vite-plugin@1.22.5 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 X=Object.defineProperty;var p=(e,t)=>X(e,"name",{value:t,configurable:!0});var U=Object.defineProperty,d=p((e,t)=>U(e,"name",{value:t,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. 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. Public source snippet (untrusted): ```json stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 1 ``` ### 6. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() The manifest identifies a Vite plugin with matching LensMCP runtime dependencies and no install lifecycle hook. Public source snippet (untrusted): ```json "dependencies": { "@babel/core": "^7.0.0", "@lensmcp/bridge": "1.22.5", "@lensmcp/core": "1.22.5", "@lensmcp/protocol-types": "1.22.5", "@lensmcp/react-instrumentation": "1.22.5", "@lensmcp/valtio-instrumentation": ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin activates through Vite and defaults its WebSocket host to loopback; its browser runtime reports console and fetch metadata for observability.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin activates through Vite and defaults its WebSocket host to loopback; its browser runtime reports console and fetch metadata for observability. Public source snippet (untrusted): ```javascript // Console for (const level of ['log','info','warn','error','debug']) { const original = console[level]; console[level] = function(...args) { try { send({ kind: 'console', level, args: args.map((a) => safe(a)) }) ``` ### 9. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/plugin.js - **Public source:** [View source]() Fetch reporting sends request URLs and status metadata, but inspected code shows no credential collection or unrelated network destination.
