    CVE-2018-12537

    Published: 14 Aug 2018Last Modified: 8 Jul 2026

    Summary:

    Details: 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.
