JSON

A flaw was found in PHP versions 8.1 before 8.1.29, 8.2 before 8.2.20, and 8.3 before 8.3.8. When using Apache and PHP-CGI on Windows, if the system is set up to use certain code pages, Windows may use the “Best-Fit” behavior to replace characters in the command line given to Win32 API functions. The PHP CGI module may misinterpret those characters as PHP options that allow a malicious user to pass options to the PHP binary being run, revealing the source code of scripts or running arbitrary PHP code on the server.

Mitigation

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
