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.

Mout是Mout团队的一个基于Javascript的为JS编程提供模块支持的代码库。 Mout 存在安全漏洞，该漏洞源于deepFillIn函数可以用来“递归地填充缺失的属性”，而deepMixIn“将对象混合到目标对象中，同时递归地混合现有的子对象”。在这两种情况下，用于递归访问目标对象的键都没有被检查，从而导致原型污染。

Vulnerability Title
Prototype Pollution
Source: CVE Program / CVE List V5
Vulnerability Description
This affects all versions of package mout. The deepFillIn function can be used to 'fill missing properties recursively', while the deepMixIn 'mixes objects into the target object, recursively mixing existing child objects as well'. In both cases, the key used to access the target object recursively is not checked, leading to a Prototype Pollution.
