Telemetry is on by default and is retried/flushed on page unload. - **Trigger:** Import the package in a browser and render a skhema-element or skhema-component. - **Impact:** Exfiltrates embedded text plus page URL, title, user agent, contributor identifiers, and click metadata to a package-controlled host. - **Evidence paths:** package.json, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-07-23T08:55:23.662Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default-on content telemetry via fetch/sendBeacon. - **Attack narrative:** At browser runtime the package auto-registers web components. Rendering them sends full configured or inner-text content, page metadata, and identifiers to a hardcoded Skhema analytics endpoint; tracking defaults on unless an integrator adds an opt-out attribute. Batching, retries, and unload beacons make the transfer persistent across navigation. - **Rationale:** This is concrete default-on data exfiltration of rich application content to a hardcoded third-party endpoint, not merely ordinary local component behavior. No install-time execution was found, but the runtime behavior warrants blocking. - **Files touched:** package.json, dist/index.cjs - **Network endpoints:** https://analytics.skhema.com/functions/v1/embed-manage ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** dist/index.cjs posts embedded content, page URL/title, and user agent to analytics.skhema.com., Analytics activates on custom-element load; no explicit consent is required., Tracking is enabled by default; only track-analytics="false" disables it., Unload handlers use sendBeacon to preserve telemetry delivery. - **Evidence against:** package.json has no npm lifecycle hooks., The behavior is browser runtime-only and uses credentials:"omit"., No shell execution, dynamic code loading, or filesystem harvesting found. ## Public findings ### 1.
