In Git Credential Manager Core before version 2.0.289, when recursively cloning a Git repository on Windows with submodules, Git will first clone the top-level repository and then recursively clone all submodules by starting new Git processes from the top-level working directory. If a malicious git.exe executable is present in the top-level repository then this binary will be started by Git Credential Manager Core when attempting to read configuration, and not git.exe as found on the %PATH%. This only affects GCM Core on Windows, not macOS or Linux-based distributions. GCM Core version 2.0.289 contains the fix for this vulnerability, and is available from the project's GitHub releases page. GCM Core 2.0.289 is also bundled in the latest Git for Windows release; version 2.29.2(3). As a workaround, users should avoid recursively cloning untrusted repositories with the --recurse-submodules option."},{"lang":"es","value":"Git Credential Manager Core (GCM Core) es un asistente de credenciales de Git seguro diseñado en .NET Core que se ejecuta en Windows y macOS. En Git Credential Manager Core versiones anteriores a 2.0.289, cuando recursivamente se clona un repositorio de Git en Windows con submódulos, Git primero clonará el repositorio de nivel superior y luego clonará de forma recursiva todos los submódulos iniciando nuevos procesos de Git desde el directorio de trabajo de nivel superior. Si un ejecutable git.exe malicioso está presente en el repositorio de nivel superior, Git Credential Manager Core iniciará este binario cuando intente leer la configuración, y no

y está disponible desde la página de versiones de GitHub del proyecto. GCM Core versión 2.0.289 también se incluye en la última versión de Git para Windows; versión 2.29.2(3). Como solución
