PYSEC-2026-3981

Quick fix

PYSEC-2026-3981 — gitpython: upgrade to the fixed version with the command below.

pip install --upgrade 'gitpython>=3.1.53'

Details

GitPython before 3.1.53 fails to properly escape section names in git config files, allowing attackers to inject arbitrary configuration directives through malicious submodule names. Attackers can inject core.sshCommand or other dangerous config keys into the victim's .git/config via create_submodule or clone_from operations, achieving remote code execution when git performs ssh operations.
