Description

AI Translation Available

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.
