CVE-2024-35241Network attack vector

Code execution via unescaped Git branch names

Published Jun 10, 2024 · Updated Apr 21, 2025

Command injection in Composer 2.0 through 2.2.23 and 2.3 through 2.7.6 allows remote attackers to execute code via crafted Git branch names. GitDownloader::getUnpushedChanges interpolates unescaped remote and local branch names into a shell command used by status, reinstall, and remove. Exploitation requires a source-installed Git dependency with an attacker-controlled branch name and user interaction to run an affected command.
