NVD Description

Note: Versions mentioned in the description apply only to the upstream php:7.4/php-xml package and not the php:7.4/php-xml package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

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.
