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.

AnalysisAI
Incorrect authorization in MongoDB Server's LDAP integration allows an authenticated user to acquire elevated privileges by exploiting stale identity retention in pooled LDAP connections. When LDAP-based authorization is configured and connection pooling is active, a reused connection may carry a prior user's LDAP identity into subsequent authorization queries, causing MongoDB to assign roles intended for a different directory principal. …

Vulnerability AssessmentAI
| Exploitation | LDAP external authorization must be explicitly enabled in MongoDB's configuration (net.tls, security.ldap settings) - this is a non-default, enterprise-specific deployment mode. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N) scores 7.6 (High). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation is to apply MongoDB's vendor-released patch once confirmed via the Jira tracker SERVER-130785 (https://jira.mongodb.org/browse/SERVER-130785); a specific fixed version is not independently confirmed from available references and should be verified against MongoDB's official release notes or security advisories. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify and document all MongoDB Server deployments with LDAP authentication enabled, particularly those in production environments handling sensitive data. …
