Feiten
GitLab heeft kwetsbaarheden verholpen in GitLab CE/EE versies voor 18.3.6, 18.4.4, en 18.5.2.
Interpretaties
De kwetsbaarheden omvatten onder andere de mogelijkheid voor aanvallers om Duo-authenticatieflows te verwijderen, toegang te krijgen tot gevoelige informatie via GraphQL-abonnementen, en het omzeilen van toegangscontroles op GitLab Pages. Deze kwetsbaarheden kunnen leiden tot ongeautoriseerde toegang en gegevenslekken, wat de integriteit en vertrouwelijkheid van gebruikersdata in gevaar brengt.
Oplossingen
GitLab heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
