{"id":"CVE-2026-91457","kind":"vulnerability","aliases":["CVE-2026-91457"],"related":[],"title":"Oracle Outside In: Image Export SDK flaw lets local attacker take over","description":"Vulnerability in the Oracle Outside In Technology product of Oracle Fusion Middleware (component: Outside In Image Export SDK).   The supported version that is affected is 8.5.8. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle Outside In Technology executes to compromise Oracle Outside In Technology.  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of Oracle Outside In Technology. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts).
