A flaw was found in Envoy version 1.9.0 and older, where Envoy does not reject embedded zero characters (NUL, ASCII 0x0) when processing HTTP/1.x header values. This flaw allows remote attackers crafting header values containing embedded NUL characters to potentially bypass header matching rules, gaining access to unauthorized resources.
