How to fix?

Upgrade org.apache.commons:commons-configuration2 to version 2.7 or higher.

Overview

org.apache.commons:commons-configuration2 is a group of tools to assist in the reading of configuration/preferences files in various formats.

Affected versions of this package are vulnerable to Remote Code Execution (RCE). It uses a third-party library to parse YAML files (org.yaml:snakeyaml) which by default allows the instantiation of classes if the YAML includes special statements. Apache Commons Configuration did not change the default settings of this library. Therefore if a YAML file was loaded from an untrusted source, it could therefore load and execute code out of the control of the host application.
