Seroval affected by Denial of Service via Array serialization
Overriding encoded array lengths by replacing them with an excessively large value causes the deserialization process to significantly increase processing time.
Mitigation:
Seroval no longer encodes array lengths.
Instead, it computes length using Array.prototype.length during deserialization.
