CVE-2019-11243 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. In Kubernetes v1.12.0-v1.12.4 and v1.13.0, the rest.AnonymousClientConfig() method returns a copy of the provided config, with credentials removed (bearer token, username/password, and client certificate/key data). In the affected versions, rest.AnonymousClientConfig() did not effectively clear service account credentials loaded using rest.InClusterConfig(). EPSS estimates a 1.49% chance of exploitation in the next 30 days.
