Su p\u00fablico objetivo son los usuarios que no se sienten c\u00f3modos usando Git en la l\u00ednea de comandos. Git GUI tiene una funci\u00f3n para clonar repositorios. Inmediatamente despu\u00e9s de que el clon local est\u00e9 disponible, la GUI de Git lo procesar\u00e1 autom\u00e1ticamente y, entre otras cosas, ejecutar\u00e1 un corrector ortogr\u00e1fico llamado `aspell.exe` si se encuentra. La GUI de Git se implementa como un script Tcl/Tk. Debido al desafortunado dise\u00f1o de Tcl en Windows, la ruta de b\u00fasqueda cuando se busca un ejecutable _siempre incluye el directorio actual_. Por lo tanto, los repositorios maliciosos pueden incluir un `aspell.exe` en su directorio de nivel superior que se ejecuta mediante la GUI de Git sin darle al usuario la oportunidad de inspeccionarlo primero, es decir, ejecutando c\u00f3digo que no es de confianza. Este problema se solucion\u00f3 en la versi\u00f3n 2.39.1. Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar deben evitar usar la GUI de Git para la clonaci\u00f3n.
