Summary

CVE-2023-38647 is a new vulnerability that allows an attacker to execute arbitrary code through unbounded deserialization in SnakeYAML. Specifically, they can manipulate the deserialization of java.net.URLClassLoader and javax.script.ScriptEngineManager in Helix REST start and Workflow creation. This can lead to remote code execution, impacting all versions below 1.3.0 of helix-core and helix-rest. To mitigate this risk, it's recommended to stop using YAML-based configuration and workflow creation in the short term. In the long term, organizations should upgrade to Helix version 1.3.0.
