An update that solves three vulnerabilities can now be installed.
## Description:
This update for python-GitPython fixes the following issues:
* CVE-2026-87817: failure to properly validade the git directory location
allows attackers to impersonate the git directory using tracked files and
execute arbitrary code by placing pre-commit hooks in the tracked hooks
directory (bsc#1279905).
* CVE-2026-87818: failure to restrict the `--no-index` option in the high-
level diff API allows attackers to read arbitrary filesystem paths as
repository operands and create content-dependent Boolean oracles
(bsc#1279906).
* CVE-2026-87819: quadratic backtracking in the `Actor.name_email_regex`
regular expression allows attackers to cause CPU exhaustion and a DoS via a
commit with a malformed author field (bsc#1279907).
