Seroval affected by Denial of Service via Array serialization

Source: GitHub Advisory Database (reviewed) High CVE-2026-23957

Packages

EcosystemPackageAffectedFixed in
npm seroval < 1.4.1 1.4.1

Details

As written in the advisory (Markdown source, shown as plain text).

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.
