Possible prototype pollution in metadata record, when using meta decorator
Impact
Possible prototype pollution for the MetadataRecord, when merged with a base class' metadata object, in meta decorator from the @aedart/support package.
The likelihood is questionable, given that a class' metadata can only be set or altered when the class is decorated via meta(). Furthermore, object(s) of sensitive nature would have to be stored as metadata, before this can become a vulnerability.

Has been patched in version 0.6.1.
