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 flagged dependency bridge is declared alongside the package’s matching LensMCP instrumentation dependencies and is used for the plugin’s development telemetry. The source shows no lifecycle hook or concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-20T02:55:54.142Z - **Finished:** 2026-10-20T02:56:53.540Z - **Download time:** 1792 ms - **Static scan time:** 49 ms - **AI review time:** 57556 ms - **Total time:** 59398 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 confirmed attack was identified. When used in Vite development, the plugin captures browser telemetry for its LensMCP observability bridge. - **Trigger:** A consumer configures the plugin in a Vite development server; client injection is enabled by default. - **Impact:** Development telemetry, including console data and fetch metadata, reaches the local LensMCP bridge; no unrelated recipient or concrete attack behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-20T02:56:53.540Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin starts a token-protected WebSocket bridge, bound to loopback by default, and the injected runtime sends browser events to it. - **Rationale:** The flagged dependency bridge is declared alongside the package’s matching LensMCP instrumentation dependencies and is used for the plugin’s development telemetry. The source shows no lifecycle hook or concrete malicious behavior. - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares LensMCP bridge and instrumentation dependencies and identifies the LensMCP repository., The plugin defaults to Vite development serving, binds the bridge to loopback by default, and creates a per-start token., The injected runtime sends bounded console and fetch event data over the WebSocket to the plugin bridge., The runtime WebSocket uses the plugin host and port and includes the generated token. - **Evidence against:** The inspected source supports the package’s declared development observability function; no unrelated recipient or concrete attack behavior was identified. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.6. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.6 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.
