YAML File Parsing Vulnerability in Apache Commons Configuration

CVE-2020-1953

What is CVE-2020-1953?

Apache Commons Configuration is susceptible to vulnerabilities due to its use of a third-party library for YAML file parsing. By default, this library allows the instantiation of classes if the YAML includes specific statements. As a result, if a YAML file from an untrusted source is loaded, it may lead to the execution of code that the host application cannot control. This poses significant security risks, particularly in applications that process YAML files from potentially malicious origins.
