Advisory Weakness Curation

Open Redirect in serve-static 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.

serve-static Open Redirect When using serve-static middleware and it's configured to mount at the root it creates an open redirect on the site. For example: If a user visits `http://example.com//www.google.com/%2e%2e` they will be redirected to `www.google.com`
