CVE-2026-82053: Improper Session Handling in MongoDB Server LDAP Authorization Integration Leads to Incorrect Role Assignment
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.

Event History
Frequently Asked Questions
Which deployments are exposed to this issue?
Deployments using MongoDB Server's LDAP authorization integration may be exposed, specifically where the affected pooled LDAP connection behavior occurs. The resulting privilege impact depends on the LDAP directory's access control configuration.
What does an attacker need to exploit it?
An attacker needs to be an authenticated user. Exploitation does not require user interaction and can allow the user's authorization queries to run under an unintended retained LDAP identity.
What is the potential impact?
An authenticated user may receive incorrect role assignments and potentially obtain elevated privileges not intended by the deployment's authorization policy. The vulnerability affects confidentiality and integrity; no availability impact is indicated.
