Problemet skyldes manglende korrekt kontrol af v\u00e6rtsnavnet, hvor der blev tilladt kodning af tegn i formatet %xx (URL-kodning). En angriber kunne bruge procentkodning til at inds\u00e6tte escape-sekvenser i v\u00e6rtsnavnet, der manipulerer terminaludgangen.\n<p>P\u00e5 denne m\u00e5de kan teksten i autentificeringsprompten \u00e6ndres, hvilket skaber en illusion for brugeren om, at de henvender sig til et andet repository, s\u00e5 n\u00e5r de henvender sig til angriberens repository, indtaster de brugernavn og adgangskode fra et andet v\u00e6rtsnavn. Angrebet kan udf\u00f8res ved at k\u00f8re rekursiv kloning af undermoduler med kommandoen \u00abgit clone \u2014recurse-submodules\u00bb, hvor et af undermodulerne kan anmode om adgangskode til et andet v\u00e6rtsnavn, men indtastningen vil blive sendt til v\u00e6rten med angriberens repository.      <\/p>\n<li class=\"l\"> CVE-2024-52006 \u2014 i implementeringen af protokollen \u00abcredential helper\u00bb, der bruges til at sende legitimationsoplysninger ved adgang til repositories med begr\u00e6nset adgang, er der opdaget et gennembrud, der tillader indspr\u00f8jtning af carriage return-tegn ved angivelse af en specielt formateret URL. Da protokollen manipulerer linje-for-linje data, kan tilf\u00f8jelse af carriage return-tegn bruges til at adskille datablokke og organisere overf\u00f8rsel af adgangskoden til det forkerte. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/\"   title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a>. Muligheden for at udf\u00f8re et angreb afh\u00e6nger af fortolkningen af carriage return-tegnet som linjeskaber i forskellige implementeringer af protokollen \u00abcredential helper\u00bb. For eksempel er Git Credential Manager, der er skrevet i C#\/.NET, s\u00e5rbar over for denne problematik.    <\/ul>\n<p>Brugere, der ikke har mulighed for at opdatere Git, anbefales at undg\u00e5 at henvende sig til utjekkede eksterne repositories ved hj\u00e6lp af kommandoen \u00abgit clone\u00bb med flaget \u00ab\u2014recurse-submodules\u00bb, samt at undg\u00e5 brugen af credential helpers ved kloning af offentlige repositories. Udover selve Git er der ogs\u00e5 udgivet rettelser til at blokere for disse s\u00e5rbarheder for GitHub Desktop (CVE-2025-23040), Git LFS (CVE-2024-53263) og Git Credential Manager
