CVE-2026-23493: Pimcore ENV Variables and Cookie Informations are exposed in http_error_log

Pimcore is an Open Source Data & Experience Management Platform. Prior to 12.3.1 and 11.5.14, the http_error_log file stores the $_COOKIE and $_SERVER variables, which means sensitive information such as database passwords, cookie session data, and other details can be accessed or recovered through the Pimcore backend. This vulnerability is fixed in 12.3.1 and 11.5.14.
