Description SMASH SMASH 2023-10-02 07:48:11 UTC 
Composer is a dependency manager for PHP. Users publishing a composer.phar to a
public web-accessible server where the composer.phar can be executed as a php
file may be subject to a remote code execution vulnerability if PHP also has
`register_argc_argv` enabled in php.ini. Versions 2.6.4, 2.2.22 and 1.10.27
patch this vulnerability. Users are advised to upgrade. Users unable to upgrade
should make sure `register_argc_argv` is disabled in php.ini, and avoid
publishing composer.phar to the web as this is not best practice.
