In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below
7.4.11, when PHP is processing incoming HTTP cookie values, the cookie
names are url-decoded. This may lead to cookies with prefixes like __Host
confused with cookies that decode to such prefix, thus leading to an
attacker being able to forge cookie which is supposed to be secure. See
also CVE-2020-8184 for more information.
