Overview
Affected versions of this package are vulnerable to HTTP Request Smuggling via the static file handler when it serves GET responses without consuming the request body. An attacker can inject and have the server process unintended HTTP requests by embedding arbitrary HTTP requests inside the body of a GET request on HTTP/1.1 keep-alive connections.
