{"id":"CVE-2026-87327","kind":"vulnerability","aliases":["CVE-2026-87327"],"related":[],"title":"Oracle JD Edwards EnterpriseOne Tools: adjacent-network flaw exposes and alters data","description":"Vulnerability in the JD Edwards EnterpriseOne Tools product of Oracle JD Edwards (component: Enterprise Infrastructure SEC).  Supported versions that are affected are 9.2.0.0-9.2.26.5. Difficult to exploit vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the JD Edwards EnterpriseOne Tools executes to compromise JD Edwards EnterpriseOne Tools.  Successful attacks of this vulnerability can result in  unauthorized access to critical data or complete access to all JD Edwards EnterpriseOne Tools accessible data as well as  unauthorized update, insert or delete access to some of JD Edwards EnterpriseOne Tools accessible data. CVSS 3.1 Base Score 5.9 (Confidentiality and Integrity impacts).
