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 entry point performs request-driven routing for documented Levo API and SEO paths, while the other inspected exports parse caller-supplied data. The manifest contains no install lifecycle hook, and no unrelated collection or autonomous behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-31T21:14:25.619Z - **Finished:** 2026-10-31T21:14:53.086Z - **Download time:** 510 ms - **Static scan time:** 38 ms - **AI review time:** 26918 ms - **Total time:** 27467 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 identified; the package provides a request-driven Next.js proxy and header parsing helpers. - **Trigger:** The middleware acts when the consumer invokes it for a matching request path. - **Impact:** No malicious behavior was identified in the inspected package source. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T21:14:53.086Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It rewrites designated requests to configured or default Levo API hosts; helper exports parse supplied header and route data. - **Rationale:** The entry point performs request-driven routing for documented Levo API and SEO paths, while the other inspected exports parse caller-supplied data. The manifest contains no install lifecycle hook, and no unrelated collection or autonomous behavior was found. - **Network endpoints:** https://public-api.levo.so, https://insights-api.levo.so ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest defines build, type-check, clean, and development scripts, with no install lifecycle hook., The middleware defaults to Levo’s public API and insights API hosts and rewrites requests only for designated proxy paths., SEO file proxying is limited to robots.txt, llms.txt, and sitemap XML paths, with an exclusion option., Geo and language helpers process caller-provided headers and return parsed values; no network or file operations were found. ## Affected versions and remediation This report applies to @levo-so/next-middleware@0.3.33. - Review the evidence and your use of @levo-so/next-middleware@0.3.33 before allowing it.
