AI Security Review
scanned 3d ago · by lpm-firewall-aiThe 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.
Static reason
High-risk behavior combination matched malicious policy.
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.
Mechanism
The SDK posts the full page URL, hostname, error details, and stack trace to its analytics endpoint; telemetry is enabled by default.
AI 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.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Unknown with medium false-positive risk.
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.
