CVE-2026-67322
Full vulnerability record from the local CVENow database.
Description
GitPython before 3.1.52 is vulnerable to environment-variable exfiltration in Repo.clone_from(). The caller-supplied remote URL is passed through Git.polish_url(), which on non-Cygwin platforms calls os.path.expandvars() on the URL before invoking git clone. An attacker who controls the clone URL can embed $NAME or ${NAME} tokens that are expanded to the values of the hosting process's environment variables (e.g., AWS_SECRET_ACCESS_KEY or GITHUB_TOKEN). The resulting URL, now containing the secret, is transmitted over the network to an attacker-controlled host during the clone attempt, disclosing the secret.

"value": "GitPython anterior a la 3.1.52 es vulnerable a la exfiltración de variables de entorno en Repo.clone_from(). La URL remota proporcionada por el llamador se pasa a través de Git.polish_url(), que en plataformas que no son Cygwin llama a os.path.expandvars() en la URL antes de invocar git clone. Un atacante que controla la URL de clonación puede incrustar tokens $NAME o ${NAME} que se expanden a los valores de las variables de entorno del proceso de alojamiento (p. ej., AWS_SECRET_ACCESS_KEY o GITHUB_TOKEN). La URL resultante, ahora que contiene el secreto, se transmite a través de la red a un host controlado por el atacante durante el intento de clonación, revelando el secreto."
