CVE ID:CVE-2019-18802
Description:An issue was discovered in Envoy 1.12.0. An untrusted remote client may send an HTTP header (such as Host) with whitespace after the header content. Envoy will treat "header-value " as a different string from "header-value" so for example with the Host header "example.com " one could bypass "example.com" matchers.
Test IDs: 1.3.6.1.4.1.25623.1.1.4.2020.0722.1   1.3.6.1.4.1.25623.1.1.10.2020.0147   1.3.6.1.4.1.25623.1.0.853732   1.3.6.1.4.1.25623.1.0.853082
