NVD Description

Note: Versions mentioned in the description apply only to the upstream composer package and not the composer package as distributed by Alpine. See How to fix? for Alpine:3.15 relevant fixed versions and status.

Composer is an open source dependency manager for the PHP language. In affected versions windows users running Composer to install untrusted dependencies are subject to command injection and should upgrade their composer version. Other OSs and WSL are not affected. The issue has been resolved in composer versions 1.10.23 and 2.1.9. There are no workarounds for this issue.
