Hi,

The following vulnerability was published for composer.

CVE-2022-24828[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
