CVE-2026-125119— Mongoose: Connection-level sanitizeFilter not applied

Quick assessment

Affected

Automattic mongoose

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.

Mongoose 是一个专为异步环境设计的 MongoDB 对象建模工具。在 6.0.0 至 6.13.12、7.8.13、8.24.7 和 9.11.4 版本中，Mongoose 将连接级别的选项存储在中，但及查询类型转换逻辑却检查了其他选项位置，并未读取该配置。因此，若应用程序通过或启用，并将攻击者可控的对象传入查询过滤器，则连接会报告防护已启用，而实际查询选择器对象却未经过净化。攻击者可构造包含查询操作符的密码值，从而在不匹配预期字面密码的情况下成功匹配账户记录。值得注意的是，通过进行的全局配置

Vulnerability Title

Mongoose: Connection-level sanitizeFilter not applied

Source: CVE Program / CVE List V5

Vulnerability Description

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. From 6.0.0 until 6.13.12, 7.8.13, 8.24.7, and 9.11.4, Mongoose stores the connection-level sanitizeFilter option in Connection.config, but Query.prototype._castConditions() and query casting check other option locations and do not read that configuration. An application that enables sanitizeFilter through mongoose.connect() or createConnection() and passes an attacker-controlled object into a query filter therefore receives a connection that reports the defense as enabled while query selector objects remain unsanitized. A crafted password value using a query operator can match an account record without the expected literal password, while global configuration through mongoose.set('sanitizeFilter') and per-query Model.find().sanitizeFilter() remain unaffected. This issue is fixed in versions 6.13.12, 7.8.13, 8.24.7, and 9.11.4.
