GitPython: Unguarded git read-tree option forwarding in IndexFile.from_tree/reset/merge_tree enables arbitrary file overwrite

Summary IndexFile.fromtree, IndexFile.reset → fromtree and IndexFile.mergetree append caller-influenced treeish strings positionally to git read-tree with no unsafe-option guard, no allowunsafeoptions parameter, and no -- separator. git read-tree --index-output= writes the resulting index to an...

OESA-2026-3249 python-GitPython security update

GitPython is a python library used to interact with git repositories, high-level like git-porcelain, or low-level like git-plumbing. Security Fixes: GitPython before 3.1.52 is vulnerable to environment-variable exfiltration in Repo.clonefrom. The caller-supplied remote URL is passed through...

PT-2026-78400

Name of the Vulnerable Software and Affected Versions GitPython versions prior to 3.1.58 Description A remote code execution issue exists in the Repo.init function. The software forwards unsafe git options without proper validation, allowing an attacker to provide a template parameter that points...

GitPython Code Execution

The vulnerability of the checkunsafeoptions function in the Python library for interacting with Git repositories, GitPython, is related to the lack of measures taken to neutralize special elements. Exploiting this vulnerability may allow a remote attacker to execute arbitrary code...

CVE-2026-67323

A flaw was found in GitPython where it fails to properly sanitize dangerous Git options. This vulnerability allows an attacker to inject arbitrary commands when using functions like Repo.archive and git.lsremote, potentially leading to arbitrary code execution. Additionally, functions such as...

GHSA-P538-C434-8V24 GitPython: Arbitrary file truncation via git rev-list --output argument injection in unguarded Commit.count

Summary Commit.count forwards kwargs into revlist with no checkunsafeoptions guard the guard exists only in the sibling iteritems, commit.py:341. git rev-list --output= opens and truncates the target file to 0 bytes before revision parsing, so countoutput='/victim' destroys/blanks an arbitrary...

GitPython: Incomplete unsafe_git_archive_options denylist omits --add-file / --add-virtual-file, enabling arbitrary file read via Repo.archive()

Target: gitpython-developers/GitPython Tested: HEAD 07e80555 2026-07-25, latest release 3.1.55, git version 2.50.1 Summary Repo.archive does call the option guard, so this is not a missing-guard report. The guard is present and working; the denylist it consults is incomplete. python...

GitPython: Unguarded git option forwarding in IndexFile.checkout() and TagReference.create() enables arbitrary file overwrite and arbitrary file read

Target: gitpython-developers/GitPython Tested: HEAD 07e80555 2026-07-25, latest release 3.1.55, git version 2.50.1 Reported instances: 2 exploitable, from a sweep of 14 unguarded call sites Summary GitPython blocks dangerous git options through Git.checkunsafeoptions, gated per method by an...

CVE-2026-67324

A flaw was found in GitPython. A remote attacker can exploit a vulnerability where the software fails to properly recognize joined short-option forms e.g., -u when enforcing its default unsafe-option gate. This allows the attacker to bypass security checks and execute arbitrary commands during a...

Linux Distros Unpatched Vulnerability : CVE-2026-67323

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive and git.lsremote, allowing command injection vi...

CVE-2026-67324

GitPython 3.1.50 fails to recognize joined short-option forms such as -u the short form of --upload-pack= when enforcing its default unsafe-option gate. When an application passes attacker-influenced clone options into Repo.clonefrom..., multioptions=..., allowunsafeoptions=False, an attacker can...

CVE-2026-67323

GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive and git.lsremote, allowing command injection via options such as --exec/--upload-pack leading to arbitrary command execution. Additionally, Repo.itercommits and Repo.blame do not check...

CVE-2026-67325

GitPython before 3.1.51 contains an incomplete command injection blocklist that fails to account for git's long-option prefix abbreviation feature. Attackers can bypass the unsafe options guard by using abbreviated option names like uploadp instead of uploadpack, which git resolves to dangerous...

CVE-2026-67324

GitPython 3.1.50 contains a vulnerability where joined short options like -u are not recognized when enforcing the default unsafe-option gate. This allows an attacker-controlled clone to supply -u and bypass the gate that blocks --upload-pack/-u, causing Git to execute the specified helper during...
