Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GitPython versions before 3.2.1 are vulnerable when an application passes an attacker-influenced submodule path to create_submodule. A path of ".git/hooks" causes the submodule to be cloned into the repository's hooks directory before the path is rejected, so an attacker-supplied post-checkout hook can be planted there. The hook then runs on later git operations such as checkout, giving code execution; exploitation needs a hook name that is free in .git/hooks. Upgrade to GitPython 3.2.1 or later.
