CVE-2026-67324

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.

Summary		(es) GitPython 3.1.50 no reconoce las formas de opciones cortas unidas, como -u[valor] (la forma corta de --upload-pack=[valor]), al aplicar su puerta de opción insegura predeterminada. Cuando una aplicación pasa opciones de clonación influenciadas por el atacante a Repo.clone_from(..., multi_options=..., allow_unsafe_options=False), un atacante puede proporcionar -u[helper] para eludir la puerta que bloquea --upload-pack/-u, haciendo que Git ejecute el comando auxiliar especificado durante la clonación. Corregido en 3.1.51.
