             Summary: Security fix for SnakeYAML
                 Key: NIFI-11142
                 URL: https://issues.apache.org/jira/browse/NIFI-11142
             Project: Apache NiFi
          Issue Type: Improvement
          Components: MiNiFi
            Reporter: Robert Liszli
             Fix For: 1.20.0


*Fix for:*
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.
