CVE-2026-79767

5.5 MEDIUM 0.4% exploit odds Fix listed Auth & access Web app

What it is

Gardener implements the automated management and operation of Kubernetes clusters as a service. Prior to 1.142.6, 1.143.3, 1.144.2, and 1.145.0, the customverbauthorizer admission plugin's mustCheckProjectMembers manage-members check compares changes to User subjects but does not account for Group or ServiceAccount subjects in Project.spec.members. A project administrator who lacks manage-members permission can add arbitrary Group or ServiceAccount subjects, including the system:authenticated Group, and thereby grant broad project access. The resulting access can include Shoots, Secrets, and cloud provider credentials. This issue is fixed in versions 1.142.6, 1.143.3, 1.144.2, and 1.145.0.
