CVE-2026-110859

GitPython is a Python library used to interact with Git repositories. In versions prior to 3.1.49, the GitConfigParser.set_value() method did not validate values for newlines, allowing for the injection of malicious paths into Git configuration.

GitPython is a Python library used to interact with Git repositories. Prior to version 3.1.48, a vulnerability allowed attackers to manipulate files outside the repository's .git directory due to insufficient validation of reference paths.

GitPython is a Python library used to interact with Git repositories. In versions prior to 3.1.47, the _clone() function improperly validates multi_options, allowing malicious hooks to be executed during repository cloning.

GitPython is a Python library used to interact with Git repositories. From version 3.1.30 to before version 3.1.47, the library blocks dangerous Git options, but equivalent Python kwargs can bypass that check, leading to arbitrary command execution.

GitPython before 3.1.59 fails to safely re-serialize multi-line git-config values during write operations, potentially turning dormant quoted values into active directives like core.hooksPath. Attackers can craft config files with embedded newlines that become live after any GitPython config write, enabling arbitrary code execution.

GitPython 3.1.50 fails to recognize joined short-option forms such as -u<value> (the short form of --upload-pack=<value>) when enforcing its default unsafe-option gate. When an application passes attacker-influenced clone options into Repo.clone_from(..., multi_options=..., allow_unsafe_options=False), an attacker can supply -u<helper> to bypass the gate that blocks --upload-pack/-u, causing Git to execute the specified helper command during clone. Fixed in 3.1.51.

GitPython before 3.1.32 does not block insecure non-multi options in clone and clone_from. This issue exists because of an incomplete fix for CVE-2022-24439.

GitPython from 3.1.62 before 3.2.0 contains a symlink-following flaw in Submodule.move(), which checks the destination only lexically and does not reject symbolic links in intermediate path components. An untrusted repository can commit a symlink such as vendor pointing outside the worktree, so an application moving an initialized submodule beneath it relocates the checkout externally and corrupts the index and .gitmodules.

GitPython from 3.1.30 before 3.2.0 contains a remote code execution vulnerability in Remote.pull() whose unsafe-option guard inspects only keyword arguments, not the positional refspec. An attacker controlling the refspec can supply --upload-pack=<command> to execute OS commands as the calling process over local-path or SSH transports.

GitPython before 3.2.0 contains a remote code execution vulnerability because Git.ls_remote forwards URLs without check_unsafe_protocols validation. Attackers can supply ext:: remote-helper URLs to execute commands when git permits the ext transport, while merge_base and IndexFile.move also accept unguarded option injection.
