{"id":"CVE-2026-101368","kind":"vulnerability","aliases":["CVE-2026-101368"],"related":[],"title":"Oracle REST Data Services: unauthenticated request lets attackers read and change some data","description":"Vulnerability in Oracle REST Data Services (component: Backend-as-a-Service).  Supported versions that are affected are 24.2.0-26.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle REST Data Services.  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in  unauthorized update, insert or delete access to some of Oracle REST Data Services accessible data as well as  unauthorized read access to a subset of Oracle REST Data Services accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts).
