CVE-2026-83091

Low-Privilege HTTP Attack Yields Unauthorized Data Access in Oracle Field Service

Published Sep 15, 2026 CVSS 3.1 · 7.6 High EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle Field Service product of Oracle E-Business Suite (component: Internal Operations). 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 Oracle Field Service. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Field Service accessible data as well as unauthorized update, insert or delete access to some of Oracle Field Service accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Field Service. CVSS 3.1 Base Score 7.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L).

Analysis

Technical impact

A vulnerability in Oracle Field Service allows a low privileged attacker with network access via HTTP to gain unauthorized access to critical data. The flaw is an insecure direct object reference (CWE-284), enabling the attacker to read, update, insert, or delete data, and also to trigger a partial denial of service. The impact affects confidentiality (high), integrity (low), and availability (low), which together raise the overall threat level.

Affected Systems

The affected product is Oracle Corporation: Oracle Field Service, specifically the Internal Operations component. Versions 12.2.3 through 12.2.15 are impacted. The flaw is reachable over standard HTTP connections exposed to the network.

Risk and Exploitability

The CVSS 3.1 score of 7.6 indicates a high severity vulnerability. The EPSS score is less than 1%, suggesting a low probability of exploitation at this time, and the vulnerability is not listed in the CISA KEV catalog. Attackers would typically target the HTTP interface, require only low privileges, and no user interaction. If exploited, the attacker could compromise a breadth of data and partially disrupt service availability.
