How to fix?

Upgrade io.fabric8:kubernetes-client to version 5.11.2, 5.8.1, 5.7.4, 5.4.2, 5.3.2, 5.1.2, 5.0.3 or higher.

Overview

io.fabric8:kubernetes-client is a This client provides access to the full Kubernetes & OpenShift REST APIs via a fluent DSL.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data due to insecure deserialization in the unmarshalYaml method. Due to an improperly configured YAML parsing, this will allow a local and privileged attacker to supply malicious YAML.

Details

Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.

Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
