CVE-2026-82070— Insufficiently Protected Credentials in MongoDB Server Diagnostic Reporting Interface

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 服务器的诊断报告接口存在安全漏洞，允许拥有监控权限的已认证用户访问来自并发管理操作的、保护不足的凭据。同样的凭据在服务器日志输出中会被正确屏蔽，但诊断接口却遗漏了相应的屏蔽处理。成功利用该漏洞需要一个具有监控级别权限的有效认证会话，并会导致明文凭据的暴露，从而可能使得攻击者能够模拟其他用户（包括特权账户）的身份。

Vulnerability Title
Insufficiently Protected Credentials in MongoDB Server Diagnostic Reporting Interface
Source: CVE Program / CVE List V5
Vulnerability Description
A security issue in MongoDB Server's diagnostic reporting interface allows an authenticated user with monitoring privileges to access insufficiently protected credentials from concurrent administrative operations. The same credentials are properly redacted in server log output, but the diagnostic interface omits equivalent redaction. Successful exploitation requires a valid authenticated session with monitoring-level permissions and results in exposure of cleartext credentials that could enable impersonation of other users, including privileged accounts.
