NewCVE-2023-54404 (opens in a new tab)How to fix?
There is no fixed version for zod.
Overview
zod is a TypeScript-first schema declaration and validation library with static type inference
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the handleArrayResult parse logic in $ZodArray, which accumulates every validation issue for each failing element in a large array with no cap or early termination. An attacker can submit a large array to an application using an array schema without a length constraint, causing the process to allocate excessive issue objects and crash due to out-of-memory conditions.
