NVD Description

Note: Versions mentioned in the description apply only to the upstream php:8.1/php-opcache package and not the php:8.1/php-opcache package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when receiving headers from HTTP server, the headers missing a colon (:) are treated as valid headers even though they are not. This may confuse applications into accepting invalid headers.
