CVE-2023-54404— Zod 4.6.5 Uncontrolled Resource Consumption via Array Validation

Quick assessment

Affected
colinhacks zod
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Zod 模式验证库（版本 4.6.5 及之前）存在一个不受控的资源消耗漏洞。攻击者可以通过向使用未设置长度约束的数组模式（array schema）的应用程序提交一个大型数组，从而耗尽系统内存。该漏洞源于 中的 解析逻辑：该逻辑会为每个验证失败的元素累积所有验证问题，且没有设置上限或提前终止机制。这会导致进程分配过多的“问题对象”（issue objects），最终因内存溢出（out-of-memory）而崩溃。

Vulnerability Title
Zod 4.6.5 Uncontrolled Resource Consumption via Array Validation
Source: CVE Program / CVE List V5
Vulnerability Description
Zod schema-validation library through 4.6.5 contains an uncontrolled resource consumption vulnerability that allows attackers to exhaust memory by submitting a large array to an application using an array schema without a length constraint. Attackers can exploit the handleArrayResult parse logic in $ZodArray, which accumulates every validation issue for each failing element with no cap or early termination, causing the process to allocate excessive issue objects and crash due to out-of-memory conditions.
