CVE-2022-24828: Missing input validation can lead to command execution in composer
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.

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.
