CVE-2026-67323

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.

Summary		(es) GitPython anterior a la versión 3.1.51 no protege contra opciones peligrosas de Git pasadas como argumentos de palabra clave en Repo.archive() y git.ls_remote(), permitiendo la inyección de comandos a través de opciones como --exec/--upload-pack (lo que lleva a la ejecución arbitraria de comandos). Además, Repo.iter_commits() y Repo.blame() no verifican los argumentos de revisión que comienzan con un guion, por lo que una revisión como --output=[path] puede hacer que Git abra y trunque un archivo arbitrario. La explotación requiere una aplicación que pase argumentos controlados por el atacante a estos métodos.
