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 package is a browser SDK whose network behavior is activated by an explicit render call and is consistent with loading its hosted widget. No lifecycle hook or concrete malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-11T17:48:14.731Z - **Finished:** 2026-09-11T17:49:07.970Z - **Download time:** 518 ms - **Static scan time:** 50 ms - **AI review time:** 52670 ms - **Total time:** 53239 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 malicious attack surface is confirmed. Explicit TravelRule.render use loads a Zerohash CDN widget and reports failures with limited browser and JWT-derived metadata. - **Trigger:** A consumer calls TravelRule.render in a browser. - **Impact:** The consumer browser may execute the configured Zerohash widget and send diagnostic metadata to Zerohash endpoints. - **Review source:** ai\_review - **Reviewed:** 2026-09-11T17:49:07.970Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote widget loading and failure telemetry. - **Rationale:** The package is a browser SDK whose network behavior is activated by an explicit render call and is consistent with loading its hosted widget. No lifecycle hook or concrete malicious behavior was found. - **Files touched:** dist/index.js - **Network endpoints:** https://sdk-cdn.zerohash.com, https://grafana-faro-collector.zerohash.com/collect ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** At render time, the SDK injects a remote Zerohash web-component module and posts load-failure telemetry., The telemetry payload can include browser user agent, page origin, and selected JWT claims., The manifest has no lifecycle scripts or dependency declarations., The declarations describe a browser TravelRule widget API and match the distributed implementation. - **Evidence against:** No install-time execution, shell/process use, filesystem access, secret harvesting, or persistence was found., Remote loading is limited to explicit widget rendering and uses fixed Zerohash CDN URLs., No concrete malicious behavior or unconsented consumer-project mutation was found. ## Affected versions and remediation This report applies to @zerohash-sdk/travel-rule-js@0.5.3. - Review the evidence and your use of @zerohash-sdk/travel-rule-js@0.5.3 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.
