N\u00e4r en URL av typen «https:\/\/evil.com?host=github.com\/» anges, kommer hanteraren av autentiseringsuppgifter vid anslutning till v\u00e4rden evil.com att \u00f6verf\u00f6ra autentiseringsparametrarna som \u00e4r angivna f\u00f6r github.com. Problemet uppst\u00e5r vid utf\u00f6rande av operationer som «git clone», inklusive behandling av URL:er f\u00f6r submoduler (till exempel vid utf\u00f6rande av «git submodule update» kommer URL:erna som anges i .gitmodules-filen fr\u00e5n repositoryn automatiskt att behandlas). S\u00e5rbarheten utg\u00f6r den st\u00f6rsta riskerna i situationer d\u00e4r utvecklaren klonar ett repository utan att se URL:en, till exempel vid arbete med submoduler, eller i system som utf\u00f6r automatiska \u00e5tg\u00e4rder, till exempel i paketbyggningsskript.<\/p>\n
