Summary

Composer is a dependency manager for PHP. In the affected package composer/composer versions 2.0.0-alpha1 through 2.2.23, and 2.3.0-RC1 through 2.7.6, the "composer install" command running inside a "git/hg" repository which has specially crafted branch names can lead to command injection. This requires cloning untrusted repositories. As a workaround, avoid cloning potentially compromised repositories.
