CVE-2018-16471

Priority
Description
There is a possible XSS vulnerability in Rack before 2.0.6 and 1.6.11.
Carefully crafted requests can impact the data returned by the `scheme`
method on `Rack::Request`. Applications that expect the scheme to be
limited to 'http' or 'https' and do not escape the return value could be
vulnerable to an XSS attack. Note that applications using the normal
escaping mechanisms provided by Rails may not impacted, but applications
that bypass the escaping mechanisms, or do not use them may be vulnerable.
