{"id":"CVE-2026-91494","kind":"vulnerability","aliases":["CVE-2026-91494"],"related":[],"title":"Oracle Identity Manager Connector: LDAP Gateway flaw lets unauthenticated network attackers modify data","description":"Vulnerability in the Oracle Identity Manager Connector product of Oracle Fusion Middleware (component: LDAP Gateway).  Supported versions that are affected are 12.2.1.4.0 and  14.1.2.1.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Identity Manager Connector.  Successful attacks of this vulnerability can result in  unauthorized creation, deletion or modification access to critical data or all Oracle Identity Manager Connector accessible data as well as  unauthorized access to critical data or complete access to all Oracle Identity Manager Connector accessible data.
