Source inspection found no install-time execution or malicious execution chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-08-08T13:37:39.332Z - **Finished:** 2026-08-08T13:39:03.084Z - **Download time:** 752 ms - **Static scan time:** 478 ms - **AI review time:** 82520 ms - **Total time:** 83752 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 malicious attack surface. The browser embed performs first-party analytics for rendered Skhema elements and provides a track-analytics opt-out. - **Trigger:** A \ or \ with a contributor ID connects in a browser. - **Impact:** Posts the embedded content and page metadata to Skhema's analytics endpoint; no host credentials are included. - **Evidence paths:** package.json, dist/index.cjs, dist/index.es.js, dist/embed.min.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-08T13:39:03.084Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Batched first-party embed analytics via fetch/sendBeacon. - **Rationale:** The scanner's exfiltration signal corresponds to disclosed, package-aligned browser analytics for the embed component, not credential theft or covert payload behavior. Source inspection found no install-time execution or malicious execution chain. - **Files touched:** package.json, dist/index.cjs, dist/index.es.js, dist/embed.min.js, README.md - **Network endpoints:** https://analytics.skhema.com/functions/v1/embed-manage, https://analytics.skhema.com, https://skhema.com, https://app.skhema.com/save ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** Runtime posts embed content, page URL/title, and user agent to analytics.skhema.com., Analytics is enabled unless the rendered element sets track-analytics="false"., A 24-hour \_sk cookie deduplicates tracked content hashes. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Network activity is confined to the named Skhema analytics endpoint and uses credentials:"omit"., Tracking activates only when browser custom elements are connected and a contributor ID is present., No credential harvesting, filesystem access, shell execution, dynamic code execution, or remote payload loading found. ## Affected versions and remediation This report applies to @skhema/embed@0.3.0. - Review the evidence and your use of @skhema/embed@0.3.0 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.
