{"id":"CVE-2026-91238","kind":"vulnerability","aliases":["CVE-2026-91238"],"related":[],"title":"Oracle SOA Suite Fabric Layer flaw lets low-privileged users change data over HTTP","description":"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. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle SOA Suite.  Successful attacks of this vulnerability can result in  unauthorized creation, deletion or modification access to critical data or all 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 7.1 (Integrity and Availability impacts).
