Vulnerability from pysec - Published: 2023-08-28 18:15 - Updated: 2023-09-05 22:26GitPython is a python library used to interact with Git repositories. When resolving a program, Python/Windows look for the current working directory, and after that the PATH environment. GitPython defaults to use the git command, if a user runs GitPython from a repo has a git.exe or git executable, that program will be run instead of the one in the user's PATH. This is more of a problem on how Python interacts with Windows systems, Linux and any other OS aren't affected by this. But probably people using GitPython usually run it from the CWD of a repo.

Vulnerability from osv_homebrew – Published: 2026-08-13 17:24 – Updated: 2026-09-10 00:46 – Source websiteSummary
When resolving a program, Python/Windows look for the current working directory, and after that the PATH environment (see big warning in https://docs.python.org/3/library/subprocess.html#popen-constructor). GitPython defaults to use the git command, if a user runs GitPython from a repo has a git.exe or git executable, that program will be run instead of the one in the user's PATH.
Details
This is more of a problem on how Python interacts with Windows systems, Linux and any other OS aren't affected by this. But probably people using GitPython usually run it from the CWD of a repo.
The execution of the git command happens in
https://github.com/gitpython-developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/cmd.py#L277
https://github.com/gitpython-developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/cmd.py#L983-L996
And there are other commands executed that should probably be aware of this problem.
PoC
On a Windows system, create a git.exe or git executable in any directory, and import or run GitPython from that directory
python -c "import git"
The git executable from the current directory will be run.
Impact
An attacker can trick a user to download a repository with a malicious git executable, if the user runs/imports GitPython from that directory, it allows the attacker to run any arbitrary commands.
Possible solutions
- Default to an absolute path for the git program on Windows, like
C:\\Program Files\\Git\\cmd\\git.EXE(default git path installation). - Require users to set the
GIT_PYTHON_GIT_EXECUTABLEenvironment variable on Windows systems. - Make this problem prominent in the documentation and advise users to never run GitPython from an untrusted repo, or set the
GIT_PYTHON_GIT_EXECUTABLEenv var to an absolute path. - Resolve the executable manually by only looking into the
PATHenvironment variable (suggested by @Byron)
[!NOTE] This vulnerability was reported via email, and it was decided to publish it here and make it public, so the community is aware of it, and a fix can be provided.

BREW-SHALLOW-BACKUP-CVE-… (GHSA-WFM5-V35H-VWF4)
Vulnerability from osv_homebrew – Published: 2026-08-13 17:34 – Updated: 2026-09-17 17:55 – Source websiteSummary
When resolving a program, Python/Windows look for the current working directory, and after that the PATH environment (see big warning in https://docs.python.org/3/library/subprocess.html#popen-constructor). GitPython defaults to use the git command, if a user runs GitPython from a repo has a git.exe or git executable, that program will be run instead of the one in the user's PATH.
Details
This is more of a problem on how Python interacts with Windows systems, Linux and any other OS aren't affected by this. But probably people using GitPython usually run it from the CWD of a repo.
The execution of the git command happens in
https://github.com/gitpython-developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/cmd.py#L277
https://github.com/gitpython-developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/cmd.py#L983-L996
And there are other commands executed that should probably be aware of this problem.
PoC
On a Windows system, create a git.exe or git executable in any directory, and import or run GitPython from that directory
python -c "import git"
The git executable from the current directory will be run.
Impact
An attacker can trick a user to download a repository with a malicious git executable, if the user runs/imports GitPython from that directory, it allows the attacker to run any arbitrary commands.
Possible solutions
- Default to an absolute path for the git program on Windows, like
C:\\Program Files\\Git\\cmd\\git.EXE(default git path installation). - Require users to set the
GIT_PYTHON_GIT_EXECUTABLEenvironment variable on Windows systems. - Make this problem prominent in the documentation and advise users to never run GitPython from an untrusted repo, or set the
GIT_PYTHON_GIT_EXECUTABLEenv var to an absolute path. - Resolve the executable manually by only looking into the
PATHenvironment variable (suggested by @Byron)
[!NOTE] This vulnerability was reported via email, and it was decided to publish it here and make it public, so the community is aware of it, and a fix can be provided.

BREW-STANDARDEBOOKS-CVE-… (GHSA-WFM5-V35H-VWF4)
Vulnerability from osv_homebrew – Published: 2026-08-13 17:41 – Updated: 2026-09-11 17:23 – Source websiteSummary
When resolving a program, Python/Windows look for the current working directory, and after that the PATH environment (see big warning in https://docs.python.org/3/library/subprocess.html#popen-constructor). GitPython defaults to use the git command, if a user runs GitPython from a repo has a git.exe or git executable, that program will be run instead of the one in the user's PATH.
Details
This is more of a problem on how Python interacts with Windows systems, Linux and any other OS aren't affected by this. But probably people using GitPython usually run it from the CWD of a repo.
The execution of the git command happens in
https://github.com/gitpython-developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/cmd.py#L277
https://github.com/gitpython-developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/cmd.py#L983-L996
And there are other commands executed that should probably be aware of this problem.
PoC
On a Windows system, create a git.exe or git executable in any directory, and import or run GitPython from that directory
python -c "import git"
The git executable from the current directory will be run.
Impact
An attacker can trick a user to download a repository with a malicious git executable, if the user runs/imports GitPython from that directory, it allows the attacker to run any arbitrary commands.
Possible solutions
- Default to an absolute path for the git program on Windows, like
C:\\Program Files\\Git\\cmd\\git.EXE(default git path installation). - Require users to set the
GIT_PYTHON_GIT_EXECUTABLEenvironment variable on Windows systems. - Make this problem prominent in the documentation and advise users to never run GitPython from an untrusted repo, or set the
GIT_PYTHON_GIT_EXECUTABLEenv var to an absolute path. - Resolve the executable manually by only looking into the
PATHenvironment variable (suggested by @Byron)
[!NOTE] This vulnerability was reported via email, and it was decided to publish it here and make it public, so the community is aware of it, and a fix can be provided.

https://github.com/gitpython-developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/cmd.py#L277
https://github.com/gitpython-developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/cmd.py#L983-L996
And there are other commands executed that should probably be aware of this problem.
PoC
On a Windows system, create a git.exe or git executable in any directory, and import or run GitPython from that directory
python -c "import git"
The git executable from the current directory will be run.
Impact
An attacker can trick a user to download a repository with a malicious git executable, if the user runs/imports GitPython from that directory, it allows the attacker to run any arbitrary commands.
Possible solutions
- Default to an absolute path for the git program on Windows, like
C:\\Program Files\\Git\\cmd\\git.EXE(default git path installation). - Require users to set the
GIT_PYTHON_GIT_EXECUTABLEenvironment variable on Windows systems. - Make this problem prominent in the documentation and advise users to never run GitPython from an untrusted repo, or set the
GIT_PYTHON_GIT_EXECUTABLEenv var to an absolute path. - Resolve the executable manually by only looking into the
PATHenvironment variable (suggested by @Byron)
[!NOTE] This vulnerability was reported via email, and it was decided to publish it here and make it public, so the community is aware of it, and a fix can be provided.
