Overview

seroval is a Stringify JS values

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via createTypedArrayNode, createBigIntTypedArrayNode, and createDataViewNode in base-primitives.ts, and the corresponding deserialization paths in deserializer.ts, when processing typed arrays, BigInt typed arrays, or DataView objects whose length exceeds the internal base64 cap. An attacker can supply an oversized typed array or DataView to trigger unbounded memory allocation or processing, crashing the process.
