CVE-2026-61248Network attack vector

Server takeover via undisclosed LDAP flaw

Published Aug 18, 2026 · Updated Aug 18, 2026

Unspecified flaw in Oracle Internet Directory 12.2.1.4.0 and 14.1.2.1.0 allows remote authenticated users to take over the service via LDAP. Oracle has disclosed only that the issue is in the OID LDAP Server component and has not published the affected request path, function, or validation error that lets LDAP-sourced input cross a trust boundary. Reachability requires network access to LDAP plus valid low-privileged credentials; Oracle rates the result as full confidentiality, integrity, and availability compromise, with possible impact beyond the directory service itself.
