Description
### Impact Users publishing a composer.phar to a public web-accessible server where the composer.phar can be executed as a php file may be impacted if PHP also has `register_argc_argv` enabled in php.ini. ### Patches 2.6.4, 2.2.22 and 1.10.27 patch this vulnerability. ### Workarounds Make sure `register_argc_argv` is disabled in php.ini, and avoid publishing composer.phar to the web as this really should not happen.
