GHSA-WVPP-8HX9-P66J GitPython: Unsafe git option guard bypass via split_single_char_options=False short-option token smuggling enables command execution

Summary The checkunsafeoptions guard can be bypassed on every guarded method clone/clonefrom, fetch/pull/push, lsremote, itercommits, blame, archive by combining a single-character kwarg with splitsinglecharoptions=False. The guard's candidate list omits the smuggled option, but transformkwarg...

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...

GHSA-3F7W-8RR8-F37F 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-2026-67325

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-2026-67323

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-2026-67324

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...
