Versions of `serve-static` prior to 1.6.5 ( or 1.7.x prior to 1.7.2 ) are affected by an open redirect vulnerability on some browsers when configured to mount at the root directory.

## Proof of Concept

A link to `http://example.com//www.google.com/%2e%2e` will redirect to `//www.google.com/%2e%2e`

Some browsers will interpret this as `http://www.google.com/%2e%2e`, resulting in an external redirect.

## Recommendation

Version 1.7.x: Update to version 1.7.2 or later. Version 1.6.x: Update to version 1.6.5 or later.
