Description Pedro Sampaio 2019-04-25 20:14:15 UTC

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()

Comment 7 Hardik Vyas 2019-05-22 09:45:12 UTC

Gluster ships very old kubernetes version v1.5.5 which is not affected by this vulnerability.

Comment 8 Hardik Vyas 2019-05-22 09:45:14 UTC

Statement:

This issue does not affect the version of Kubernetes(embedded in heketi) shipped with Red Hat Gluster Storage 3 as it does not contain the vulnerable functionality.
