Critical security vulnerability in snakeyaml

This vulnerability is fixed in snakeyaml 2.0 and requires a backwards incompatible change in the constructor
https://nvd.nist.gov/vuln/detail/CVE-2022-1471

SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization. Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization.
