{"id":"CVE-2026-91488","kind":"vulnerability","aliases":["CVE-2026-91488"],"related":[],"title":"Oracle Identity Manager Connector: Generic REST flaw lets low-privileged users modify data","description":"Vulnerability in the Oracle Identity Manager Connector product of Oracle Fusion Middleware (component: Generic REST).  Supported versions that are affected are 12.2.1.4.0 and  14.1.2.1.0. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Identity Manager Connector executes 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. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts).
