> Fix DefaultParamsReader RCE vulnerability:
> The metadata loading [https://github.com/apache/spark/blob/18aebd8eb86b554e7aab38baca1e5de24df19a57/mllib/src/main/scala/org/apache/spark/ml/util/ReadWrite.scala#L565] does not verify the class,
> and then the reflection invocation [https://github.com/apache/spark/blob/18aebd8eb86b554e7aab38baca1e5de24df19a57/mllib/src/main/scala/org/apache/spark/ml/util/ReadWrite.scala#L568] will trigger arbitrary code execution if malicious class name is written to a designed metadata file.
>  
> This become a security vulnerability because the code is executed in Spark driver which might be run as ROOT permission.
