    GitPython validates a submodule's ".git" path only after cloning into it (RCE)

    GitPython is a python library used to interact with Git repositories. Prior to 3.2.1, create_submodule() in git/objects/submodule/base.py accepts an attacker-influenced submodule path such as .git/hooks and invokes _clone_repo() before safely rejecting the destination. In 3.1.x, _validate_repo_path() does not exist and the call succeeds silently, while in 3.2.0 and later affected revisions the check in git/index/base.py raises ValueError only after the clone has written to disk and does not remove the planted file. An attacker-controlled submodule can therefore place an executable post-checkout hook that a later Git operation executes. Exploi

    GitPython 3.1.62 before 3.2.0 Symlink Path Traversal via Submodule.move()

    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 before 3.2.0 Arbitrary File Read via Head.checkout() Branch Name

    GitPython before 3.2.0 contains an argument injection vulnerability in Head.checkout() that allows remote attackers to read arbitrary files by supplying a branch name parsed as a git option. Attackers can host a repository whose default branch is named --pathspec-from-file=<path>, causing cloning applications that check out the active branch to leak file contents through GitCommandError messages.

    GitPython 3.1.30 before 3.2.0 Command Injection via Remote.pull() Refspec

    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. Attackers 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 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.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.

    GitPython before 3.2.0 ReDoS via _re_actor_epoch in parse_actor_and_date

    GitPython before 3.2.0 contains a regular expression denial of service vulnerability in the _re_actor_epoch pattern used by parse_actor_and_date on author, committer, and tagger lines. Attackers can serve repositories with commit or tag objects containing long space-filled lines lacking a valid epoch or timezone, causing quadratic backtracking and CPU exhaustion.

    GitPython before 3.2.0 Environment Variable Disclosure via .gitmodules Submodule Name

    GitPython before 3.2.0 contains an information disclosure vulnerability that allows malicious repositories to expand environment variables via separate_git_dir in Repo._clone(), which omits expand_vars=False when calling Git.polish_url(). Attackers can craft a .gitmodules submodule name containing variable syntax so that clone plus submodule_update exposes secrets in .git/modules directory names and DEBUG logs.

    GitPython before 3.1.62 Path Traversal via gitmodules path

    GitPython before 3.1.62 does not validate the `path` field read from an untrusted .gitmodules file when updating submodules. While a prior fix (GHSA-hmq2-w58f-27jc) added Submodule._validated_name() to constrain the `name` field, and GitPython's own containment guard Submodule._to_relative_path() is applied in add() and move(), Submodule.update() derives the absolute checkout location from the raw `path` value without that guard. A .gitmodules entry containing directory traversal components (e.g., path = ../../../tmp/escaped) can therefore cause directories to be created via os.makedirs() outside the repository working tree, populated from th

    GitPython before 3.1.58 Path Traversal via .gitmodules Submodule Name

    GitPython before 3.1.58 fails to validate submodule names from .gitmodules files, allowing attackers to create Git repositories at arbitrary filesystem paths outside the intended clone directory. Attackers can craft malicious repositories with traversal sequences in submodule names that GitPython processes during submodule initialization, creating attacker-controlled Git repositories at escaped filesystem locations.

    GitPython before 3.1.58 Config Injection via option-name

    GitPython before 3.1.58 contains a config-name injection vulnerability in the option-name validator that allows attackers to forge arbitrary git-config directives by injecting equals signs, hash symbols, and whitespace into option names. Attackers can inject malicious option names like 'sshCommand = touch /tmp/RCE #' to execute arbitrary commands via core.sshCommand or core.hooksPath on the next git operation.

    GitPython before 3.1.58 contains a command execution vulnerability in the check_unsafe_options guard that can be bypassed by combining a single-character kwarg with split_single_char_options=False. Attackers can supply a crafted kwargs dictionary to guarded methods like clone_from to emit a joined token parsed as --upload-pack, enabling arbitrary OS command execution at default allow_unsafe_options=False.

    GitPython versions before 3.1.58 contain an arbitrary file overwrite vulnerability in IndexFile.from_tree, IndexFile.reset, and IndexFile.merge_tree methods that append caller-influenced treeish strings to git read-tree without option validation or argument separation. Attackers can inject the --index-output option to overwrite arbitrary files with a valid git-index blob, destroying existing file content at attacker-controlled writable paths.

    GitPython versions before 3.1.54 contain a remote code execution vulnerability in the check_unsafe_options guard that can be bypassed by smuggling git options inside single-character kwarg values. Attackers can supply crafted option dictionaries to clone_from, fetch, pull, push, ls_remote, iter_commits, blame, or archive methods to execute arbitrary OS commands via the --upload-pack parameter.

    GitPython before 3.1.54 contains an incomplete denylist in unsafe_git_clone_options that omits --template, allowing attackers to achieve arbitrary command execution during clone operations. Attackers can supply --template pointing to a directory containing malicious post-checkout hooks that execute when git clones the repository.

    GitPython before 3.1.55 fails to disable environment variable expansion in Remote.create() and Submodule.add() URL handling, allowing attackers to exfiltrate secrets by supplying URLs containing variable references. Attackers can craft URLs with environment variable tokens that are expanded into .git/config and .gitmodules, then transmitted to attacker-controlled hosts during fetch or pull operations.

    GitPython before 3.1.56 Arbitrary File Truncation via Commit.count

    GitPython before 3.1.56 contains an argument injection vulnerability in the Commit.count() method, which forwards keyword arguments to 'git rev-list' without the check_unsafe_options guard present in the sibling iter_items method. An attacker who can control options passed to Commit.count (e.g., via an application that forwards a user-supplied options dict) can supply output=<path>, causing 'git rev-list --output=<path>' to open and truncate the target file to zero bytes before revision parsing. This allows destruction/blanking of an arbitrary file at the process's privilege level (no content control, 0-byte truncation).
