How to fix?

Upgrade Chainguard php-8.1 to version 8.1.29-r0 or higher.

NVD Description

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

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 "Best-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.
