CVE-2019-10223: Information Exposure

November 5, 2019 (updated November 29, 2019)

A security issue was discovered in the kube-state-metrics versions. By default, the kube-state-metrics metrics only expose metadata about Secrets. However, a combination of the default kubectl behavior and this new feature can cause the entire secret content to end up in metric labels thus inadvertently exposing the secret content in metrics.
