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 flagged source implement Vite instrumentation and a local WebSocket event bridge consistent with the package's stated purpose. The scanner signals do not establish an attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-09T10:43:59.046Z - **Finished:** 2026-10-09T10:44:29.379Z - **Download time:** 503 ms - **Static scan time:** 38 ms - **AI review time:** 29791 ms - **Total time:** 30333 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 plugin that sends browser instrumentation and development events to its bridge. - **Trigger:** A project enables the plugin in Vite and runs the development server. - **Impact:** The inspected behavior supports local development observability; no concrete malicious effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:44:29.379Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin starts a WebSocket bridge, defaults its host to 127.0.0.1, and injects a browser client that sends events to that bridge. - **Rationale:** The inspected entrypoint and flagged source implement Vite instrumentation and a local WebSocket event bridge consistent with the package's stated purpose. The scanner signals do not establish an attack surface. ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exports its Vite plugin through index.js and lists LensMCP bridge and instrumentation packages as runtime dependencies., The plugin runs when enabled as a Vite plugin, defaults its WebSocket host to 127.0.0.1, and starts the bridge on the configured host and port., The injected browser client sends instrumentation and development-server events over that WebSocket; the inspected excerpts show no credential collection or unrelated outbound destination. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.22.2. - Review the evidence and your use of @lensmcp/vite-plugin@1.22.2 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 V=Object.defineProperty;var p=(e,t)=>V(e,"name",{value:t,configurable:!0});var $=Object.defineProperty,d=p((e,t)=>$(e,"name",{value:t,configurable:!0}),"u");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 Dependency Evidence - **Category:** Dependency - **Confidence:** 92.0% - **Path:** package.json - **Public source:** [View source]() The package exports its Vite plugin through index.js and lists LensMCP bridge and instrumentation packages as runtime dependencies. Public source snippet (untrusted): ```json "type": "module", "main": "./index.js", "module": "./index.js", "types": "./index.d.ts", "exports": { "./package.json": "./package.json", ".": { "types": "./index.d.ts", "import": "./index.js", "default": "./index. ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 92.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The plugin runs when enabled as a Vite plugin, defaults its WebSocket host to 127.0.0.1, and starts the bridge on the configured host and port.
