- CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Description
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.
