CVE-2026-91536
Vulnerability in the Oracle SOA Suite product of Oracle Fusion Middleware (component: Fabric Layer). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTPS to compromise Oracle SOA Suite. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle SOA Suite accessible data as well as unauthorized read access to a subset of Oracle SOA Suite accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle SOA Suite. CVSS 3.1 Base Score 5.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L).
