CVE-2026-82053Network attack vector

Privilege escalation via stale pooled LDAP identity

Published Sep 8, 2026 · Updated Sep 10, 2026

Incorrect authorization in MongoDB Server allows remote authenticated users to gain unintended roles through stale pooled LDAP identities. WrappedConnection returns an end-user-bound LDAP connection to the pool without unbinding, while getConnectionWithOptions skips rebinding when no query user is configured. Affected releases are 7.0.0 through 7.0.40, 8.0.0 through 8.0.29, and 8.3.0 through 8.3.8; LDAP authorization, connection pooling, and no ldapQueryUser are required.
