CVE-2018-12537
This allow unfiltered values to inject a new header in the client request or server response.
Does this matter?
Lower severity and a low EPSS score (2.48%). Track it; it rarely justifies an emergency change on its own.
Description
In Eclipse Vert.x version 3.0 to 3.5.1, the HttpServer response headers and HttpClient request headers do not filter carriage return and line feed characters from the header value. This allow unfiltered values to inject a new header in the client request or server response.
