CVE-2026-67324 GitPython 3.1.50 Authentication Bypass via Joined Short Options

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 is vulnerable to a command injection issue due to an incomplete blocklist that does not account for git’s long-option prefix abbreviation. Attackers can bypass the unsafe options guard by using abbreviated option names (for example, upload_p instead of upload_pack); Git re...

gitpython: GitPython: Arbitrary code execution via command injection due to unguarded Git options

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-R9MR-M37C-5FR3 GitPython: Unsafe git option guard bypass via single-character kwarg value token smuggling enables arbitrary command execution

Summary GitPython's checkunsafeoptions guard the control introduced by CVE-2026-42215 / GHSA-2f96 and hardened since can be bypassed for every guarded method clone/clonefrom, fetch/pull/push, lsremote, itercommits, blame, archive by smuggling an option token inside the VALUE of a single-character...

Arbitrary Argument Injection

Overview GitPython is a python library used to interact with Git repositories Affected versions of this package are vulnerable to Arbitrary Argument Injection via the checkunsafeoptions process. An attacker can execute arbitrary commands by smuggling a malicious option token inside the value of a...

Overview GitPython is a python library used to interact with Git repositories Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs through Git.checkunsafeoptions in git/cmd.py. An attacker can execute arbitrary commands by supplying abbreviated unsafe option...

GitPython unsafe clone option gate bypass through joined short options

GitPython version 3.1.50 blocks unsafe git clone options such as --upload-pack, -u, --config, and -c unless callers explicitly pass allowunsafeoptions=True. However, the default unsafe-option gate does not recognize joined short-option forms such as -u/path/to/helper. Git itself accepts -u as the...

Command Injection

Overview GitPython is a python library used to interact with Git repositories Affected versions of this package are vulnerable to Command Injection via the canonicalizeoptionname function in git/cmd.py. An attacker can execute a local helper command by supplying joined short clone options such as...

PT-2026-67305

Name of the Vulnerable Software and Affected Versions GitPython versions prior to 3.1.51 Description An incomplete command injection blocklist allows attackers to bypass the unsafe options guard. The issue stems from the check unsafe options function and canonicalize option name function, which...

PT-2026-67304

Name of the Vulnerable Software and Affected Versions GitPython version 3.1.50 Description An issue exists where the software fails to recognize joined short-option forms, such as -u, which is the short form of --upload-pack=, when enforcing its default unsafe-option gate. If an application passe...

vim: arbitrary command execution via modeline sandbox bypass

A flaw was found in Vim. A modeline is used to set specific editor options directly from a text file. However, the complete, guitabtooltip, printheader options and the mapset function lack proper security checks, allowing an attacker to bypass restrictions and cause arbitrary OS command execution...
