How to fix?

Upgrade Debian:unstable python-git to version 3.1.61-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-git package and not the python-git package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

GitPython 3.1.59 fails to restrict the --no-index option in the high-level diff API, allowing attackers to read arbitrary filesystem paths as repository operands. Attackers can combine --no-index with -I/--ignore-matching-lines to create a content-dependent Boolean oracle, repeatedly querying local files to recover single-line secrets through distinguishable success or error responses.
