Name of the Vulnerable Software and Affected Versions Kubernetes components versions prior to 1.16.0

Description The issue concerns the logging of request headers in the Kubernetes client-go library at high verbosity levels, which can lead to the disclosure of credentials to unauthorized users via logs or command output. This affects components that use basic or bearer token authentication and run at high verbosity levels.

Recommendations For versions prior to 1.16.0, consider reducing the verbosity level to prevent sensitive information from being logged. As a temporary workaround, restrict access to log files to minimize the risk of exploitation. Avoid running affected components at high verbosity levels until the issue is resolved.
