Alpine: multiple py3-gitpython packages: security update to 3.1.49-r0

critical Tenable Cloud Security Plugin ID 441048

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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 execution even when allow_unsafe_options is left at its
 default value of False. This issue has been patched in version 3.1.47. (CVE-2026-42215)

 - GitPython is a python library used to interact with Git repositories. Prior to version 3.1.47, _clone()
 validates multi_options as the original list, then executes shlex.split(" ".join(multi_options)). A string
 like "--branch main --config core.hooksPath=/x" passes validation (starts with --branch), but after split
 becomes ["--branch", "main", "--config", "core.hooksPath=/x"]. Git applies the config and executes
 attacker hooks during clone. This issue has been patched in version 3.1.47. (CVE-2026-42284)

Solution

Update the py3-gitpython library and its related packages to version 3.1.49-r0 or later.
