Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 11 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 0.5.1 - **Selected version is latest:** Yes - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package contains default-on telemetry that transmits rich caller-provided content to a vendor endpoint. This is suspicious data collection rather than evidence of malware, because it has no install hook, credential access, or hidden payload execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-01T01:33:39.712Z - **Finished:** 2026-09-01T01:34:32.044Z - **Download time:** 517 ms - **Static scan time:** 606 ms - **AI review time:** 51208 ms - **Total time:** 52332 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 embed elements automatically transmit their supplied content and page metadata. Tracking is opt-out rather than opt-in. - **Trigger:** A page loads a skhema-element or skhema-component with a contributor ID. - **Impact:** Sensitive embedded material and browsing context can be disclosed to the package vendor. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T01:34:32.044Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default-on browser telemetry posts embedded content and page metadata. - **Rationale:** The package contains default-on telemetry that transmits rich caller-provided content to a vendor endpoint. This is suspicious data collection rather than evidence of malware, because it has no install hook, credential access, or hidden payload execution. - **Files touched:** dist/index.cjs - **Network endpoints:** https://analytics.skhema.com/functions/v1/embed-manage ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The browser component sends embedded content, page URL, page title, and user agent to a Skhema analytics endpoint., Analytics is enabled unless the embedding element explicitly sets track-analytics to false., Load tracking runs when a rendered custom element has a contributor ID, without a click or separate consent action. - **Evidence against:** There are no npm install lifecycle hooks., Requests omit browser credentials., The network behavior is limited to the package's named analytics service and embed telemetry. ## Affected versions and remediation This report applies to @skhema/embed@0.5.1. - Review the evidence and your use of @skhema/embed@0.5.1 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.
