Official Description

Vulnerability in Oracle REST Data Services (component: Core). Supported versions that are affected are 24.2.0-26.1.0. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTPS to compromise Oracle REST Data Services. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle REST Data Services, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle REST Data Services accessible data as well as unauthorized access to critical data or complete access to all Oracle REST Data Services accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle REST Data Services. CVSS 3.1 Base Score 7.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:L).

Technical Analysis

CVE-2026-35266 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 7.9.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
