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 的 LDAP 授权集成中存在一个安全漏洞。在某些配置下，池化的 LDAP 连接在用户认证后可能会保留过时的认证身份。这导致后续的授权查询可能在非预期的 LDAP 身份下执行，而非预期的身份。这可能导致基于 LDAP 目录访问控制配置的角色分配错误，从而使已认证的用户获得部署的授权策略并未意图授予的提升权限。

Vulnerability Title
Improper Session Handling in MongoDB Server LDAP Authorization Integration Leads to Incorrect Role Assignment
Source: CVE Program / CVE List V5
Vulnerability Description
A security issue exists in MongoDB's LDAP authorization integration where pooled LDAP connections can retain stale authentication identities after user authentication under certain configurations. Subsequent authorization queries may execute under an unintended LDAP identity rather than the expected one. This can result in incorrect role assignments based on the LDAP directory's access control configuration, potentially allowing an authenticated user to acquire elevated privileges that were not intended by the deployment's authorization policy.
