NVD Description

Note: Versions mentioned in the description apply only to the upstream composer package and not the composer package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

Composer is a dependency Manager for the PHP language. Prior to 2.2.29 and 2.10.2, a Composer package bin entry containing .. path segments can resolve outside the package install directory and cause Composer's binary installation flow to chmod an existing host file to a world-readable and world-executable mode during composer install, update, or require. This issue is fixed in versions 2.2.29 and 2.10.2.
