Hi,

The following vulnerability was published for commons-configuration2.

CVE-2020-1953[0]:
| Apache Commons Configuration uses a third-party library to parse YAML
| files which by default allows the instantiation of classes if the YAML
| includes special statements. Apache Commons Configuration versions
| 2.2, 2.3, 2.4, 2.5, 2.6 did not change the default settings of this
| library. So 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
