{"id":"CVE-2026-91216","kind":"vulnerability","aliases":["CVE-2026-91216"],"related":[],"title":"Oracle SOA Suite: unauthenticated network flaw lets attackers take over server","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 unauthenticated attacker with network access via T3, IIOP to compromise Oracle SOA Suite.  While the vulnerability is in Oracle SOA Suite, attacks may significantly impact additional products (scope change).  Successful attacks of this vulnerability can result in takeover of Oracle SOA Suite. CVSS 3.1 Base Score 10.0 (Confidentiality, Integrity and Availability impacts).
