The provided fragment is a benign, documentation-like set of patterns for error handling in a routing library. It does not contain executable or malicious code, but it highlights a privacy risk where raw error messages could be displayed. To improve security, sanitize error messages before rendering and ensure notFound/pending components handle states without leaking sensitive details. The overall security posture is low-to-moderate based on UI-level exposure rather than code execution or data theft.
