composer: Composer is a dependency manager for PHP
CVE-2023-43655 is fixed in composer on 1 platform, first by DEBIAN-CVE-2023-43655, released September 29, 2023. It is not reported as exploited. Patch Radar priority: High.
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.
