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 found browser telemetry aligned with the Vite plugin's stated observability purpose, sent through a configurable WebSocket bridge that defaults to localhost. The inspected source did not establish a malicious attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-19T20:07:51.839Z - **Finished:** 2026-10-19T20:08:27.896Z - **Download time:** 514 ms - **Static scan time:** 47 ms - **AI review time:** 35495 ms - **Total time:** 36057 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 plugin injects browser diagnostics for its Vite observability feature and sends them to its WebSocket bridge, which defaults to the local host. - **Trigger:** A consumer enables the plugin in a Vite development server; build use requires the plugin option or environment setting. - **Impact:** The inspected behavior provides local development observability; no package-selected unrelated recipient or credential harvesting was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-19T20:08:27.896Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The injected browser runtime collects instrumentation and diagnostic events and sends them through the configured WebSocket URL to the bridge. - **Rationale:** Source inspection found browser telemetry aligned with the Vite plugin's stated observability purpose, sent through a configurable WebSocket bridge that defaults to localhost. The inspected source did not establish a malicious attack surface. - **Files touched:** package.json, index.js, lib/plugin.js - **Network endpoints:** ws://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 identifies the package and points its main and module entries to index.js; that entry exports the Vite plugin implementation., The plugin activates for Vite serve by default, with build activation controlled by applyOnBuild or an environment setting; its WebSocket host defaults to 127.0.0.1., The server bridge receives a generated token and uses the configured host and port; the browser runtime connects to the injected WebSocket URL., The runtime sends browser diagnostics and instrumentation events over that bridge, including page URL and fetch metadata, consistent with the package's Vite observability purpose. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.5. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.5 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.
