CVE-2020-1953: Improper Input Validation

March 13, 2020 (updated July 21, 2021)

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. 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.
