Vulnerability Title
protobufjs: Process-wide denial of service through unsafe option paths
Source: NVD (National Vulnerability Database)
Vulnerability Description
protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs allowed certain schema option paths to traverse through inherited object properties while applying options. A crafted protobuf schema or JSON descriptor could cause option handling to write to properties on global JavaScript constructors, corrupting process-wide built-in functionality. This vulnerability is fixed in 7.5.6 and 8.0.2.

Vulnerability Title
protobuf.js 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
protobuf.js是The protobuf.js Project开源的一个纯 JavaScript 实现，具有对node.js和浏览器的TypeScript支持的协议缓冲区实现。它易于使用，速度极快，并且通过.proto文件可以开箱即用！ protobuf.js 7.5.6之前版本和8.0.2之前版本存在安全漏洞，该漏洞源于允许某些模式选项路径遍历继承的对象属性，可能导致选项处理写入全局JavaScript构造函数的属性。
