Kubernetes client-go library logs may disclose credentials to unauthorized users
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | k8s.io/client-go | < 0.17.0 | 0.17.0 |

Details
As written in the advisory (Markdown source, shown as plain text).
The Kubernetes client-go library logs request headers at verbosity levels of 7 or higher. This can disclose credentials to unauthorized users via logs or command output. Kubernetes components (such as kube-apiserver) prior to v1.16.0, which make use of basic or bearer token authentication, and run at high verbosity levels, are affected.
