CVE-2026-82069— Improper Redaction of Query Literals in MongoDB Server Query Statistics Serialization on Sharded Cluster Router

Quick assessment

Affected
MongoDB MongoDB Server
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.

MongoDB Server是美国MongoDB公司开源的一款面向文档的数据库系统。 MongoDB Server 8.3.0版本至8.3.9之前版本存在信息泄露漏洞，该漏洞源于查询统计序列化逻辑中的条件检查不当，导致数据脱敏机制被绕过，可能使具有监控权限的用户访问其他用户操作的未脱敏搜索查询文本。

Vulnerability Title
Improper Redaction of Query Literals in MongoDB Server Query Statistics Serialization on Sharded Cluster Router
Source: CVE Program / CVE List V5
Vulnerability Description
A security issue in MongoDB Server's query statistics serialization on the router allows users with monitoring privileges to access unredacted search query text from other users' operations. An improper conditional check in the serialization logic causes the data redaction mechanism to be bypassed when processing search queries through the sharded cluster router. This results in sensitive query literals being stored and made accessible through the query statistics interface.
