Envoy Proxy Vulnerability - CVE-2019-18802

Critical
Reference: CVE-2019-18802
NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2019-18802
Title: Envoy Proxy Vulnerability
Overview:

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 quotheader-value quot as a different string from quotheader-valuequot so for example with the Host header quotexample.com quot one could bypass quotexample.comquot matchers.
