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 source matches the package's stated Next.js proxy purpose: matching requests are rewritten to Levo API hosts, while the helper exports parse supplied data. No install hooks or unrelated network behavior were found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-02T10:08:54.495Z - **Finished:** 2026-11-02T10:09:30.831Z - **Download time:** 520 ms - **Static scan time:** 20 ms - **AI review time:** 35795 ms - **Total time:** 36336 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; this package provides a Next.js proxy for Levo API and SEO file requests. - **Trigger:** The middleware runs when integrated into a Next.js app and receives a request for a configured proxy or SEO file path. - **Impact:** Expected proxy behavior for the package's stated purpose; no unrelated collection, account action, persistence, or destructive behavior was found. - **Review source:** ai\_review - **Reviewed:** 2026-11-02T10:09:30.831Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It rewrites matching requests to the configured Levo API endpoints, forwarding request headers; exported helpers parse visitor and location data from supplied values. - **Rationale:** The inspected source matches the package's stated Next.js proxy purpose: matching requests are rewritten to Levo API hosts, while the helper exports parse supplied data. No install hooks or unrelated network behavior were found. - **Network endpoints:** public-api.levo.so, insights-api.levo.so ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package entry point is dist/index.js, and the manifest declares sideEffects false., The middleware defaults to the documented Levo API hosts and rewrites matching Levo API paths to those services., The GeoIP export extracts country and language data from supplied headers; it does not make network requests., The declared npm scripts are build, type checking, cleanup, and development watch commands. ## Affected versions and remediation This report applies to @levo-so/next-middleware@0.3.34. - Review the evidence and your use of @levo-so/next-middleware@0.3.34 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.
