Quick fix

PYSEC-2026-3788 — gitpython: upgrade to the fixed version with the command below.

pip install --upgrade 'gitpython>=3.1.59'

Details

GitPython versions before 3.1.59 contain an incomplete denylist in the unsafe_git_revision_options guard that omits --contents and -S options, allowing attackers to read arbitrary files by passing these options to Repo.blame(). Attackers can supply revision values like --contents=/etc/passwd to leak file contents through the blame result returned to the caller.
