Missing input validation can lead to command execution in composer
The Composer method VcsDriver::getFileContent() with user-controlled $file or $identifier arguments is susceptible to an argument injection vulnerability. It can be leveraged to gain arbitrary command execution if the Mercurial or the Git driver are used.
This led to a vulnerability on Packagist.org and Private Packagist, i.e., using the composer.json readme field as a vector for injecting parameters into the $file argument for the Mercurial driver or via the $identifier argument for the Git and Mercurial drivers.
Composer itself can be attacked through branch names by anyone controlling a Git or Mercurial repository, which is explicitly listed by URL in a project's composer.json.
To the best of our knowledge, this was not actively exploited. The vulnerability has been patched on Packagist.org and Private Packagist within a day of the vulnerability report.

Composer is a dependency manager for the PHP programming language. Integrators using Composer code to call `VcsDriver::getFileContent` can have a code injection vulnerability if the user can control the `$file` or `$identifier` argument. This leads to a vulnerability on packagist.org for example where the composer.json's `readme` field can be used as a vector for injecting parameters into hg/Mercurial via the `$file` argument, or git via the `$identifier` argument if you allow arbitrary data there (Packagist does not, but maybe other integrators do). Composer itself should not be affected by the vulnerability as it does not call `getFileContent` with arbitrary data into `$file`/`$identifier`. To the best of our knowledge this was not abused, and the vulnerability has been patched on packagist.org and Private Packagist within a day of the vulnerability report.
