HIGH 8.8UPGRADE

CVE-2026-42215 is a high-severity flaw (CVSS 8.8) affecting gitpython. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

GitPython is a python library used to interact with Git repositories. From version 3.1.30 to before version 3.1.47, GitPython blocks dangerous Git options such as --upload-pack and --receive-pack by default, but the equivalent Python kwargs upload_pack and receive_pack bypass that check. If an application passes attacker-controlled kwargs into Repo.clone_from(), Remote.fetch(), Remote.pull(), or Remote.push(), this leads to arbitrary command exec

Why this priority

High severity
Public exploit reference

A fixed release or distro patch exists.

gitpython project gitpython UPGRADE

Affected: >= 3.1.30 and < 3.1.47

Fixed in: 3.1.47

Safe to downgrade to: a release before 3.1.30

1. Check installed version

pip show gitpython

2. UPGRADE to 3.1.47

pip install --upgrade "gitpython>=3.1.47"

3. If no update is available yet, DOWNGRADE to a release before 3.1.30

pip index versions gitpython pip install "gitpython<3.1.30"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
