CVE-2026-42334— Mongoose 注入漏洞

Mongoose: Improper Sanitization of $nor in sanitizeFilter May Allow NoSQL Injection

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Prior to 6.13.9, 7.8.9, 8.22.1, and 9.1.6, a vulnerability allows bypassing Mongoose’s sanitizeFilter query sanitization mechanism via the $nor operator. When sanitizeFilter is enabled, Mongoose wraps query operators in $eq to neutralize them. However, prior to the fix, $nor was not included in the set of logical operators that are recursively sanitized. Because $nor accepts an array (like $and and $or), and arrays do not trigger hasDollarKeys(), malicious operators such as $ne, $gt, or $regex could be injected inside a $nor clause without being sanitized. This vulnerability is fixed in 6.13.9, 7.8.9, 8.22.1, and 9.1.6.

Mongoose 注入漏洞

Mongoose是Automattic开源的一个 MongoDB 对象建模，旨在在异步环境中工作。 Mongoose 6.13.9之前版本、7.8.9之前版本、8.22.1之前版本和9.1.6之前版本存在注入漏洞，该漏洞源于通过$nor运算符绕过sanitizeFilter查询清理机制，当sanitizeFilter启用时，Mongoose将查询运算符包装在$eq中，但$nor未包含在递归清理的逻辑运算符集合中，导致恶意运算符如$ne、$gt或$regex可在$nor子句中注入而不被清理。
