  "summary": "The report highlights the issue of Kubernetes service-account token mounting and recommends an explicit opt-out for Pods that do not require API access. It explains that every Kubernetes Pod receives credentials for its assigned ServiceAccount by default, which can increase the value of a workload compromise if the token is not needed by the application. The report emphasizes that the token is not a generic password but authenticates to the Kubernetes API as the ServiceAccount, subject to RBAC and admission policies. It suggests that if an application does not need the identity provided by the token, it should be explicitly opted out to avoid unnecessary credentials in the container filesystem. The report also notes that modern Kubernetes clusters often project a short-lived, audience-scoped token, which improves lifecycle management but does not make the token harmless. It advises testing the effective mount by inspecting the rendered Pod spec and checking for the presence of the token in the container filesystem.",
