Upgrade SLES:15.3 php7-fileinfo to version 7.4.33-150200.3.46.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php7-fileinfo package and not the php7-fileinfo package as distributed by SLES.
See How to fix? for SLES:15.3 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.
