## Overview

### Summary
Path normalization for static files prevents path traversal, but opens up the ability for an attacker to ascertain the
existence of absolute path components.

### Impact
If an application uses `web.static()` (not recommended for production deployments), it may be possible for an attacker to ascertain the existence of path components.
