CVE-2019-11243
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).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.49%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
