🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

React's internal error logging remains outside the sanitization boundary.

React 18.3.1 logs the original error or component stack independently of componentDidCatch. The test suppresses that behavior and can miss Error objects during serialization. (raw.githubusercontent.com)

  • src/App.tsx#L101-L101: filter React error-boundary console breadcrumbs in the Sentry initialization path.
  • src/test/app-route-analytics-error-boundary.test.tsx#L140-L141: do not suppress the React logging path used by the privacy assertion.
  • src/test/app-route-analytics-error-boundary.test.tsx#L159-L161: inspect console arguments directly and assert that neither the original Error nor a component stack reaches the breadcrumb path.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@src/App.tsx` at line 101, Filter React error-boundary console breadcrumbs in
the Sentry initialization path around the console.error handler in App.tsx. In
src/App.tsx lines 101-101, ignore React’s original Error and component-stack
logging while preserving other console errors. In
src/test/app-route-analytics-error-boundary.test.tsx lines 140-141, stop
suppressing React’s logging path; at lines 159-161, inspect console arguments
directly and assert that neither the original Error nor a component stack
reaches the breadcrumb path.
