Vulnerability Title
Kubernetes Java client libraries unvalidated path traversal in Copy implementation
Source: NVD (National Vulnerability Database)
Vulnerability Description
Kubernetes Java client libraries in version 10.0.0 and versions prior to 9.0.1 allow writes to paths outside of the current directory when copying multiple files from a remote pod which sends a maliciously crafted archive. This can potentially overwrite any files on the system of the process executing the client code.
