CVE-2026-83490

Low-Privilege HTTP Exploit Enables Unauthorized Data Access in Oracle iRecruitment

Published Sep 15, 2026 CVSS 3.1 · 8.5 High EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle iRecruitment 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 iRecruitment. While the vulnerability is in Oracle iRecruitment, 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 Oracle iRecruitment accessible data as well as unauthorized update, insert or delete access to some of Oracle iRecruitment accessible data. CVSS 3.1 Base Score 8.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N).

Analysis

Technical impact

Oracle iRecruitment, a component of Oracle E‑Business Suite, has a vulnerability that allows a low‑privileged attacker who can reach the system over HTTP to gain unauthorized access to data and modify records. The flaw is easily exploitable and can lead to confidentiality loss for critical recruitment data and, with the scope change, potentially affect other Oracle products. The weakness is tied to improper access control, allowing exploitation with minimal effort and resulting in high impact to confidentiality; integrity is also impacted, while availability is unaffected.

Affected Systems

The affected product is Oracle Corporation's Oracle iRecruitment, part of the Oracle E‑Business Suite. Versions from 12.2.3 through 12.2.15 are vulnerable. These releases correspond to the 12.2 security patch set.

Risk and Exploitability

The CVSS base score is 8.5, indicating a high severity vulnerability. The exploitability score is very low (<1% EPSS), and the flaw is not listed in CISA’s KEV catalog, suggesting no publicly known exploits. Attackers would need only network connectivity to the HTTP interface and low‑privilege credentials; this makes the vulnerability trivial for attackers within the organization’s network. With the scope change, a successful compromise can provide unauthorized read or write access to all data exposed by Oracle iRecruitment and potentially other Oracle products.
