How to fix?

Upgrade io.vertx:vertx-core to version 3.5.2 or higher.

Overview

io.vertx:vertx-core is a tool-kit for building reactive applications on the JVM.

Affected versions of this package are vulnerable to HTTP Header Injection. The HttpServer response headers and HttpClient request headers do not check wether header name or value contain \r or \n chars. This allow unfiltered values to inject a new header in the client request or server response.
