CVE-2026-29793— Feathers 安全漏洞

NoSQL Injection via WebSocket id Parameter in MongoDB Adapter

Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. From 5.0.0 to before 5.0.42, Socket.IO clients can send arbitrary JavaScript objects as the id argument to any service method (get, patch, update, remove). The transport layer performs no type checking on this argument. When the service uses the MongoDB adapter, these objects pass through getObjectId() and land directly in the MongoDB query as operators. Sending {$ne: null} as the id matches every document in the collection. This vulnerability is fixed in 5.0.42.

Feathers 安全漏洞

Feathers是Feathers开源的一个轻量级的 Web 框架。用于使用 TypeScript 或 JavaScript 创建 API 和实时应用程序。 Feathers 5.0.0版本至5.0.42之前版本存在安全漏洞，该漏洞源于传输层未对Socket.IO客户端发送的id参数进行类型检查，当使用MongoDB适配器时可能导致查询操作符注入。
