Description
Composer Remote Code Execution vulnerability via web-accessible composer.phar
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.
Mitigation
Minimal update. May introduce new vulnerabilities or breaking changes.
