CVE-2020-13264Network attack vector

Group-maintainer cluster token disclosure via reveal control

Published Jun 19, 2020 · Updated Aug 4, 2024

Information disclosure in affected GitLab CE/EE releases allows remote authenticated users to view stored Kubernetes cluster tokens. The cluster details view retains a Show control that returns the stored service token instead of treating it as a write-only secret. A group maintainer who can open the cluster page can retrieve the token, which grants only its assigned Kubernetes permissions.
