{"id":"CVE-2026-101849","kind":"vulnerability","aliases":["CVE-2026-101849"],"related":[],"title":"Oracle E-Business Suite: Installed Base flaw exposes critical data over HTTP","description":"Vulnerability in the Installed Base product of Oracle E-Business Suite (component: Create Item Instance).  Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Installed Base.  Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Installed Base, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in  unauthorized access to critical data or complete access to all Installed Base accessible data as well as  unauthorized update, insert or delete access to some of Installed Base accessible data. CVSS 3.1 Base Score 7.6 (Confidentiality and Integrity impacts).  CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N).","summary":"Oracle E-Business Suite's Installed Base module has a flaw in its Create Item Instance component that lets a low-privileged user reach the application over HTTP.
