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. 12 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:** 1.25.8 - **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. Source inspection shows a Vite development observability plugin whose runtime reports diagnostics to a tokenized bridge, defaulting to loopback. The scanner signals align with this functionality; no malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-20T07:50:04.679Z - **Finished:** 2026-10-20T07:50:43.860Z - **Download time:** 518 ms - **Static scan time:** 51 ms - **AI review time:** 38611 ms - **Total time:** 39181 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's browser runtime sends development diagnostics to its Vite bridge, which defaults to loopback. - **Trigger:** A project configures and runs the plugin in Vite serve mode. - **Impact:** No external disclosure, credential transfer, or unauthorized account action was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-20T07:50:43.860Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The injected runtime sends diagnostic events over a tokenized WebSocket to the configured bridge; console values are bounded. - **Rationale:** Source inspection shows a Vite development observability plugin whose runtime reports diagnostics to a tokenized bridge, defaulting to loopback. The scanner signals align with this functionality; no malicious behavior was established. - **Files touched:** package.json, index.js, lib/plugin.js - **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:** The manifest points its main and import entrypoints to index.js., The plugin runs in Vite serve mode and defaults its bridge host to loopback; it creates the bridge with a generated token and optional origin restrictions., The injected browser client sends diagnostic events, including console data and fetch metadata, over its WebSocket; console values are bounded. - **Evidence against:** The inspected manifest declares no lifecycle scripts. The runtime source shows no credential collection or external telemetry recipient. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.8. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.8 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.
