CVE-2021-29472

Composer is a dependency manager for PHP. URLs for Mercurial repositories in the
root composer.json and package source download URLs are not sanitized correctly.
Specifically crafted URL values allow code to be executed in the HgDriver if
hg/Mercurial is installed on the system. The impact to Composer users directly
is limited as the composer.json file is typically under their own control and
source download URLs can only be supplied by third party Composer repositories
they explicitly trust to download and execute source code from, e.g. Composer
plugins. The main impact is to services passing user input to Composer,
including Packagist.org and Private Packagist. This allowed users to trigger
remote code execution. The vulnerability has been patched on Packagist.org and
Private Packagist within 12h of receiving the initial vulnerability report and
based on a review of logs, to the best of our knowledge, was not abused by
anyone. Other services/tools using VcsRepository/VcsDriver or derivatives may
also be vulnerable and should upgrade their composer/composer dependency
immediately. Versions 1.10.22 and 2.0.13 include patches for this issue.
