Feiten
GitLab heeft kwetsbaarheden verholpen in GitLab CE/EE.
Interpretaties
De kwetsbaarheden omvatten verschillende problemen, waaronder de mogelijkheid voor geauthenticeerde gebruikers om kwaadaardige afbeeldingen te uploaden, ongeautoriseerde acties uit te voeren door het injecteren van kwaadaardige HTML, gevoelige informatie te verkrijgen via GraphQL-queries, en het omzeilen van WebAuthn tweefactorauthenticatie. Daarnaast kunnen ongeauthenticeerde gebruikers kwaadaardige scripts injecteren in de Swagger UI en GraphQL-querycomplexiteitslimieten misbruiken, wat kan leiden tot Denial of Service (DoS) situaties.
Oplossingen
GitLab heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
