Title
Kubernetes client-go logs authorization headers at debug verbosity levels
Summary
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.
Severity
4.7 (Medium)
CWE
- CWE-532 - Inclusion of Sensitive Information in Log Files

Title
Privilege escalation from compromised node to cluster
Summary
The Kubernetes kube-apiserver in versions v1.6-v1.15, and versions prior to v1.16.13, v1.17.9 and v1.18.6 are vulnerable to an unvalidated redirect on proxied upgrade requests that could allow an attacker to escalate privileges from a node compromise to a full cluster compromise.
Severity
6.4 (Medium)
