CVE-2026-110857 GitPython before 3.2.0 Command Execution via ls_remote ext:: URLs

GitPython before 3.2.0 contains a remote code execution vulnerability that allows attackers to run commands because Git.lsremote forwards URLs without checkunsafeprotocols validation. Attackers can supply ext:: remote-helper URLs to execute commands when git permits the ext transport, while...

CVE-2026-110857

The GitPython library (versions before 3.2.0 ) is vulnerable to remote code execution due to a lack of check_unsafe_protocols validation in the Git.ls_remote function. Attackers can exploit this by supplying ext:: remote-helper URLs to execute commands, provided that the underlying git installati...

PYSEC-2026-3839 GitPython: command injection via unguarded Git options in `Repo.archive()`, `git.ls_remote()`, and arbitrary file overwrite via `Repo.iter_commits()` / `Repo.blame()`

Summary GitPython already know that --upload-pack / --exec are command-exec vectors, they are denylist in git/remote.py:535 and check by Git.checkunsafeoptions git/cmd.py:963, the thing is this check him he is only call from fetch, pull, push and clonefrom, everything else who build a git argv fr...

CVE-2026-73625: Improper Neutralization of Special Elements used in an OS Command

GitPython versions before 3.1.54 contain a remote code execution vulnerability in the checkunsafeoptions guard that can be bypassed by smuggling git options inside single-character kwarg values. Attackers can supply crafted option dictionaries to clonefrom, fetch, pull, push, lsremote, itercommit...

GHSA-4VPG-PFJ8-M33Q Duplicate Advisory: GitPython: command injection via unguarded Git options in `Repo.archive()`, `git.ls_remote()`, and arbitrary file overwrite via `Repo.iter_commits()` / `Repo.blame()`

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-956x-8gvw-wg5v. This link is maintained to preserve external references. Original Description GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive and...

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...
