CVE-2026-23957

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.
