The GitPython version has been updated in this autogenerated file, but the source file hermetic_build/common/requirements.in still specifies GitPython==3.1.43. This change will be overwritten the next time pip-compile is run. Please update the .in file to 3.1.47 as well to ensure the security fix persists.

GitPython has Command Injection via Git options bypass
CVE-2026-42215 / GHSA-rpm5-65cw-6hj4
More information
Details
Summary
GitPython blocks dangerous Git options such as
--upload-packand--receive-packby default, but the equivalent Python kwargsupload_packandreceive_packbypass that check. If an application passes attacker-controlled kwargs intoRepo.clone_from(),Remote.fetch(),Remote.pull(), orRemote.push(), this leads to arbitrary command execution even whenallow_unsafe_optionsis left at its default value ofFalse.Details
GitPython explicitly treats helper-command options as unsafe because they can be used to execute arbitrary commands:
git/repo/base.py:145-153marks clone options such as--upload-pack,-u,--config, and-cas unsafe.git/remote.py:535-548marks fetch/pull/push options such as--upload-pack,--receive-pack, and--execas unsafe.The vulnerable API paths check the raw kwarg names before they're its normalized into command-line flags:
Repo.clone_from()checkslist(kwargs.keys())ingit/repo/base.py:1387-1390Remote.fetch()checkslist(kwargs.keys())ingit/remote.py:1070-1071Remote.pull()checkslist(kwargs.keys())ingit/remote.py:1124-1125Remote.push()checkslist(kwargs.keys())ingit/remote.py:1197-1198That validation is performed by
Git.check_unsafe_options()ingit/cmd.py:948-961. The validator correctly blocks option names such asupload-pack,receive-pack, andexec.Later, GitPython converts Python kwargs into Git command-line flags in
Git.transform_kwarg()atgit/cmd.py:1471-1484. During that step, underscore-form kwargs are dashified:upload_pack=...becomes--upload-pack=...receive_pack=...becomes--receive-pack=...Because the unsafe-option check runs before this normalization, underscore-form kwargs bypass the safety check even though they become the exact dangerous Git flags that the code is supposed to reject.
In practice:
remote.fetch(**{"upload-pack": helper})is blocked withUnsafeOptionErrorremote.fetch(upload_pack=helper)is allowed and reaches helper executionThe same bypass works for:
This does not appear to affect every unsafe option. For example,
exec=is already rejected because the raw kwarg nameexecmatches the blocked option name before normalization.Existing tests cover the hyphenated form, not the vulnerable underscore form. For example:
test/test_clone.py:129-136checks{"upload-pack": ...}test/test_remote.py:830-833checks{"upload-pack": ...}test/test_remote.py:968-975checks{"receive-pack": ...}Those tests correctly confirm the literal Git option names are blocked, but they do not exercise the normal Python kwarg spelling that bypasses the guard.
PoC
python3 -m venv .venv-sec .venv-sec/bin/pip install setuptools gitdb source ./.venv-sec/bin/activatecontrol=blockedproof_exists True ...id, working directory, argv, and selected environment variable namesExample output:
This PoC does not require a malicious repository. The PoC uses that fresh blank repository. The only attacker-controlled input is the kwarg that GitPython turns into
--upload-pack.Impact
Who is impacted:
**kwargsWhat the attacker needs to control:
upload_packorreceive_packin the kwargs passed toRepo.clone_from(),Remote.fetch(),Remote.pull(), orRemote.push()From a severity perspective, this could lead to
The highest-risk environments are network-reachable services and automation systems that expose these GitPython kwargs across a trust boundary while relying on the default unsafe-option guard for protection.

GitPython: Unsafe option check validates multi_options before shlex.split transformation
CVE-2026-42284 / GHSA-x2qx-6953-8485
More information
Details
Summary
_clone()validatesmulti_optionsas the original list, then executesshlex.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.Details
The vulnerable code is in
git/repo/base.pyline 1383:Then validation runs on the original list at line 1390:
Then execution uses the transformed result at line 1392:
The check at
git/cmd.pyline 959 usesstartswith:"--branch main --config ..."does not start with"--config", so it passes. Aftershlex.split,"--config"becomes its own token and reaches git.Also affects
Submodule.update()viaclone_multi_options.PoC
Output:
Impact
Any application passing user input to
multi_optionsinclone_from(),clone(), orSubmodule.update()is vulnerable. Attacker embeds--config core.hooksPath=<dir>inside a string starting with a safe option. Check does not block it. Git executes attacker code. Same class as CVE-2023-40267.Severity

GitPython reference APIs has a path traversal vulnerability that allows arbitrary file write and delete outside the repository
CVE-2026-44243 / GHSA-7545-fcxq-7j24
More information
Details
🧾 Summary
A vulnerability in GitPython allows attackers who can supply a crafted reference path to an application using GitPython to write, overwrite, move, or delete files outside the repository’s
.gitdirectory via insufficient validation of reference paths in reference creation, rename, and delete operations.📦 Affected Versions
<= 3.1.46and currentmain(3.1.47in local checkout)🧠 Details
Vulnerability Type
Path Traversal leading to Arbitrary File Write and Arbitrary File Deletion
Root Cause
Reference paths are validated when they are resolved for reading, but are not consistently validated before filesystem write, rename, and delete operations.
SymbolicReference._check_ref_name_valid()rejects traversal sequences such as.., butSymbolicReference.create,Reference.create,SymbolicReference.set_reference,SymbolicReference.rename, andSymbolicReference.deletestill construct filesystem paths from attacker-controlled ref names without enforcing repository boundaries.Affected Code
Attack Vector
Local attack through application-controlled input passed into GitPython reference APIs
Authentication Required
None at the library boundary. In practice, exploitation requires the ability to influence ref names supplied by the consuming application.

GitPython: Newline injection in config_writer().set_value() enables RCE via core.hooksPath
CVE-2026-44244 / GHSA-v87r-6q3f-2j67
More information
Details
GitConfigParser.set_value()passes values to Python'sconfigparserwithout validating for newlines. GitPython's own_write()converts embedded newlines into indented continuation lines (e.g.\nbecomes\n\t), but Git still accepts an indented[core]stanza as a section header — so the injectedcore.hooksPathbecomes effective configuration. Any Git operation that invokes hooks (commit, merge, checkout) will then execute scripts from the attacker-controlled path.The vulnerability is not merely malformed config output: GitPython's own writer converts embedded newlines into indented continuation lines, but Git still accepts an indented
[core]stanza as a section header, so the injectedcore.hooksPathbecomes effective configuration.This was found while auditing MLRun's
project.push()method, which passesauthor_nameandauthor_emaildirectly toconfig_writer().set_value()with no sanitization. Both parameters cross a trust boundary — they are caller-supplied API inputs that end up in.git/config.PoC (standalone, no MLRun required):
Tested on GitPython 3.1.46, git 2.39+.
Impact: This is persistent repo config poisoning. Any user who can supply
author_nameorauthor_emailto an application callingconfig_writer().set_value()can redirect Git hook execution to an arbitrary path. In a multi-user or hosted environment (e.g. a shared MLRun server where multiple users push to the same repositories), one user can poison the.git/configof a shared repo and have their hooks run in the context of every subsequent Git operation by any user. On single-user deployments, the impact depends on whether the application later invokes Git hooks automatically.Remediation:
set_value()should raise on CR, LF, or NUL in values rather than silently pass them through:Rejecting is safer than stripping — a stripped newline might indicate the caller is passing unsanitized input at a higher level, and silent normalization masks that.
Affected wherever
config_writer().set_value(section, key, user_input)is called with external input.** GitPython is a dependency of DVC, MLflow, Kedro, and others — worth auditing theirset_value()call sites for externally influenced inputs.Severity

GitPython: Newline injection in config_writer() section parameter bypasses CVE-2026-42215 patch, enabling RCE via core.hooksPath
GHSA-mv93-w799-cj2w
More information
Details
Summary
The patch for CVE-2026-42215 (GitPython 3.1.49) validates newlines only in the value parameter of set_value(). The section and option parameters are passed to configparser without any newline validation. An attacker who controls the section argument can inject \n to write arbitrary section headers into .git/config, including a forged [core] section with hooksPath pointing to an attacker-controlled directory, leading to RCE when any git hook is triggered.
Details
File: git/config.py — GitPython 3.1.49 (latest patched version)
_write() formats section headers as "[%s]\n" % name. When section = "user]\n[core", this writes [user]\n[core]\n — two valid section headers — into .git/config.
PoC
Impact
Same attack outcome as CVE-2026-42215 (RCE via core.hooksPath injection). The patch is incomplete — only value is validated while section and option remain injectable.
