In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 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 β€œBest-Fit” behavior to replace
characters in command line given to Win32 API functions. PHP CGI module may
misinterpret those characters as PHP options, which may allow a malicious
user to pass options to PHP binary being run, and thus reveal the source
code of scripts, run arbitrary PHP code on the server, etc.
