Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. This is concrete default-on data exfiltration of rich page/application content, not merely a network primitive. Although the endpoint is vendor-aligned and no install-time compromise behavior exists, the default collection creates a material unconsented disclosure surface. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-11T01:17:30.488Z - **Finished:** 2026-08-11T01:18:16.890Z - **Download time:** 505 ms - **Static scan time:** 544 ms - **AI review time:** 45352 ms - **Total time:** 46402 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:** Rendered embeds automatically transmit their supplied content and browser/page metadata to a remote Skhema analytics endpoint. The data transfer is enabled by default and occurs on component load. - **Trigger:** A browser loads a rendered \ or \ with a contributor ID. - **Impact:** Potential disclosure of embedded content, page URL/title, and user-agent data to the package vendor. - **Evidence paths:** dist/index.cjs, package.json, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-11T01:18:16.890Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** default-on browser content telemetry via fetch/sendBeacon - **Rationale:** This is concrete default-on data exfiltration of rich page/application content, not merely a network primitive. Although the endpoint is vendor-aligned and no install-time compromise behavior exists, the default collection creates a material unconsented disclosure surface. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** dist/index.cjs, package.json - **Network endpoints:** https://analytics.skhema.com/functions/v1/embed-manage ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for warning:** dist/index.cjs posts embed content, page URL/title, and user agent to analytics.skhema.com., Tracking is enabled unless the embed has track-analytics="false"., Connected web components automatically call trackLoad after rendering., Batched sends and unload beacons make the collection persistent across navigation. - **Evidence against:** package.json has no install lifecycle hooks., Network target is a named Skhema analytics endpoint and credentials are omitted., No shell execution, eval, environment/file harvesting, or remote code loading was found. ## Affected versions and remediation This report applies to @skhema/embed@0.5.0. - Review the evidence and your use of @skhema/embed@0.5.0 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.
