CVE-2026-82053

Improper Session Handling in MongoDB Server LDAP Authorization Integration Leads to Incorrect Role Assignment

State: Published
Severity: 7.6 High

Reserved: Aug 27, 2026

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.
