GitPython Command Injection and Path Traversal Vulnerabilities

Publication date: 2026-08-01

Last updated on: 2026-08-01

Assigner: VulnCheck

Description
GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive() and git.ls_remote(), allowing command injection via options such as --exec/--upload-pack (leading to arbitrary command execution). Additionally, Repo.iter_commits() and Repo.blame() do not check for leading-dash revision arguments, so a revision like --output=<path> can cause Git to open and truncate an arbitrary file. Exploitation requires an application that passes attacker-controlled arguments to these methods.

Executive Summary

GitPython before 3.1.51 has a command injection vulnerability in Repo.archive() and git.ls_remote() due to unsafe handling of Git options passed as arguments. Attackers can exploit options like --exec or --upload-pack to execute arbitrary commands. Additionally, Repo.iter_commits() and Repo.blame() do not validate revision arguments, allowing attackers to pass values like --output= to overwrite files.

Impact Analysis

If you use GitPython in an application that accepts user-controlled inputs for these methods, attackers could execute arbitrary commands on your system or overwrite sensitive files. This could lead to data theft, system compromise, or denial of service.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's integrity and confidentiality requirements or HIPAA's safeguards for protected health information. Organizations may face compliance violations if exploited.

Mitigation Strategies

Upgrade GitPython to version 3.1.51 or later to address the command injection and file truncation vulnerabilities. Review applications using GitPython to ensure no attacker-controlled arguments are passed to vulnerable methods like Repo.archive(), git.ls_remote(), Repo.iter_commits(), or Repo.blame().
