NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby2.5-rubygem-rack-testsuite package and not the ruby2.5-rubygem-rack-testsuite package as distributed by SLES.

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.
