CVE-2024-35241
On the 2.x branch prior to versions 2.2.24 and 2.7.7, the `status`, `reinstall` and `remove` commands with packages installed from source via git containing specially crafted branch names in the repository can be used to execute code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Composer is a dependency manager for PHP. On the 2.x branch prior to versions 2.2.24 and 2.7.7, the `status`, `reinstall` and `remove` commands with packages installed from source via git containing specially crafted branch names in the repository can be used to execute code. Patches for this issue are available in version 2.2.24 for 2.2 LTS or 2.7.7 for mainline. As a workaround, avoid installing dependencies via git by using `--prefer-dist` or the `preferred-install: dist` config setting.
