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 10 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 1.16.11 - **Selected version is latest:** No - **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’s widget loader silently reports runtime failures to the vendor’s collector with browser and page details plus selected JWT claims. This is undisclosed runtime telemetry, so it warrants a warning; the source shows no install-time or import-time reporting. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-29T23:17:45.127Z - **Finished:** 2026-10-29T23:18:28.612Z - **Download time:** 520 ms - **Static scan time:** 40 ms - **AI review time:** 42924 ms - **Total time:** 43485 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:** Undisclosed runtime error telemetry reports widget load failures to ZeroHash’s Grafana Faro collector. - **Trigger:** A caller invokes render(), and loading the widget script fails, times out, or does not define the expected component. - **Impact:** The vendor receives browser and application context without documented disclosure or an opt-out in this package. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T23:18:28.612Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK sends a JSON POST containing error context, browser user agent, page origin, and selected JWT claims. - **Rationale:** The package’s widget loader silently reports runtime failures to the vendor’s collector with browser and page details plus selected JWT claims. This is undisclosed runtime telemetry, so it warrants a warning; the source shows no install-time or import-time reporting. - **Network endpoints:** grafana-faro-collector.dev.0hash.com, grafana-faro-collector.cert.zerohash.com, grafana-faro-collector.zerohash.com, grafana-faro-collector.cert.zerohash.eu, grafana-faro-collector.zerohash.eu ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** When widget loading fails, the runtime posts an error report to a configured Grafana Faro collector., The report includes browser user agent, page origin, failure context, and selected JWT claims such as participant and platform codes., Reporting is tied to runtime widget loading; the manifest declares no lifecycle scripts, and the README shows rendering as an explicit call. - **Evidence against:** The report is limited to widget load failures and uses ZeroHash collector endpoints., The request includes selected JWT claims, not the JWT token itself., No install-time or import-time reporting behavior was identified. ## Affected versions and remediation This report applies to @zerohash-sdk/crypto-sell-js@1.16.11. - Review the evidence and your use of @zerohash-sdk/crypto-sell-js@1.16.11 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.
