Description

Description

swagger-codegen does not properly escape parametrized parts of a URL.

For example:

    var path = "/recipient/{recipient}"
    path = path.replacingOccurrences(of: "{recipient}", with: "\(recipient)", options: .literal, range: nil)

The "recipient" variable should be URLEscaped, but it isn't. Thus, if recipient contains spaces or illegal characters, the request fails. Depending on the source of the parameters, this could also lead to vulnerable code.
