Detailsinfo

A vulnerability, which was classified as critical, was found in gitpython-developers GitPython up to 3.1.48. Affected is the function GitConfigParser.set_value. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

GitPython is a python library used to interact with Git repositories. Prior to version 3.1.49, GitConfigParser.set_value() passes values to Python's configparser without validating for newlines. GitPython's own _write() converts embedded newlines into indented continuation lines (e.g. \n becomes \n\t), but Git still accepts an indented [core] stanza as a section header — so the injected core.hooksPath becomes effective configuration. Any Git operation that invokes hooks (commit, merge, checkout) will then execute scripts from the attacker-controlled path. This issue has been patched in version 3.1.49.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-44244 since 05/05/2026. The exploitability is told to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

The vulnerability scanner Nessus provides a plugin with the ID 313244 (Linux Distros Unpatched Vulnerability : CVE-2026-44244), which helps to determine the existence of the flaw in a target environment.
