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 bundles WalletConnect error telemetry that is enabled by default and sends page-identifying details, including the full page URL, to its analytics service. This is suspicious runtime telemetry under the review rules; the inspected evidence does not establish credential exfiltration or malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-11-01T12:30:01.372Z - **Finished:** 2026-11-01T12:31:13.497Z - **Download time:** 1027 ms - **Static scan time:** 14433 ms - **AI review time:** 56663 ms - **Total time:** 72125 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 sends page-identifying details to WalletConnect’s analytics service. - **Trigger:** A browser error is reported while the widget’s WalletConnect SDK is in use. - **Impact:** The analytics service receives the page URL and error data, which may include identifying details or sensitive URL parameters. - **Evidence paths:** dist/core-wZ3Qm3IX.mjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-11-01T12:31:13.497Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK posts the full page URL, hostname, error details, and stack trace to its analytics endpoint; telemetry is enabled by default. - **Rationale:** The package bundles WalletConnect error telemetry that is enabled by default and sends page-identifying details, including the full page URL, to its analytics service. This is suspicious runtime telemetry under the review rules; the inspected evidence does not establish credential exfiltration or malicious intent. - **Files touched:** dist/core-wZ3Qm3IX.mjs, dist/multichain-widget.es.js, dist/multichain-widget.umd.js - **Network endpoints:** https://pulse.walletconnect.org/e ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package’s module entry resolves to a bundled widget that includes the flagged WalletConnect code., The error telemetry collector is enabled by default., When an error is reported, the code sends the page URL, hostname, error message, and stack trace to the analytics endpoint. - **Evidence against:** The reported behavior is error telemetry in the widget’s WalletConnect SDK; the inspected code does not show credential theft or unrelated account actions., The manifest shows no install, preinstall, or postinstall hook. ## Affected versions and remediation This report applies to @upcoming/multichain-widget@0.13.2. - Review the evidence and your use of @upcoming/multichain-widget@0.13.2 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.
