Vulnerability Details

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.

Hey @zelinh! Core has fixed the CVE by upgrading to the latest version of snakeyaml i.e. 2.0. You can do the same for the repo to fix the CVE. Thanks
