CVE-2026-83398 in Data Integrator
Summary
by MITRE • 10/21/2026
Vulnerability in the Oracle Data Integrator product of Oracle Fusion Middleware (component: Data Transforms). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Data Integrator. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Data Integrator accessible data as well as unauthorized update, insert or delete access to some of Oracle Data Integrator accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N).

The identified vulnerability resides within the Data Transforms component of Oracle Fusion Middleware's Oracle Data Integrator product, specifically affecting versions 12.2.1.4.0 and 14.1.2.0.0. This security flaw is characterized by its ease of exploitation, allowing an unauthenticated attacker to compromise the system through network access via HTTP. The absence of required authentication for this attack vector significantly lowers the barrier to entry for malicious actors, enabling remote code execution or data manipulation without prior credentials. Such a configuration represents a critical misconfiguration where sensitive administrative functions are exposed to the public internet or internal networks lacking sufficient segmentation and access controls.
From a technical perspective, the flaw likely stems from insufficient validation of input parameters within the Data Transforms module, which is responsible for processing and moving data between different systems. When an attacker sends specially crafted HTTP requests targeting this component, they can bypass intended security checks to execute unauthorized operations. This aligns with common vulnerability classes such as CWE-287 Improper Authentication or CWE-918 SQL Injection if the underlying mechanism involves database interaction through poorly sanitized inputs. The ability to manipulate data transforms suggests that the application fails to enforce strict integrity constraints on incoming payloads, allowing attackers to inject malicious logic or commands that alter how data is processed and stored.
The operational impact of this vulnerability is severe, primarily due to its high confidentiality score in the CVSS 3.1 assessment. Successful exploitation grants an attacker unauthorized access to critical data housed within Oracle Data Integrator repositories. This includes sensitive business intelligence reports, customer information, financial records, or proprietary algorithms that are managed through the platform. Beyond mere observation, the vulnerability also permits unauthorized updates, inserts, and deletes against accessible data sources. This integrity impact means attackers can corrupt datasets, inject false information into analytics pipelines, or delete essential configuration files, leading to potential business disruption, regulatory non-compliance, and loss of trust among stakeholders who rely on the accuracy of the integrated data systems.
In terms of industry standards mapping, this vulnerability exhibits characteristics consistent with ATT&CK technique T1078 Valid Accounts if authentication were bypassed via other means, but more accurately reflects T1190 Exploit Public-Facing Application due to its network-accessible nature and lack of required credentials. It also relates to CWE-20 Improper Input Validation as the root cause likely involves failing to sanitize or validate user-supplied data before processing it within the transform logic. The high availability impact is not present, but the combination of high confidentiality and moderate integrity impacts results in a CVSS Base Score of 8.2, indicating a High severity rating that demands immediate attention from security operations teams.
Mitigation strategies must focus on both technical remediation and architectural hardening. Oracle should apply the latest available patches or updates for versions 12.2.1.4.0 and 14.1.2.0.0 to address the specific code flaw in the Data Transforms component. In the interim, organizations should implement network-level controls such as Web Application Firewalls configured with rulesets designed to detect and block anomalous HTTP requests targeting Oracle middleware endpoints. Additionally, restricting access to these services via IP whitelisting or VPN tunnels can prevent unauthenticated external actors from reaching the vulnerable interface. Regular vulnerability scanning and penetration testing focused on integration platforms are essential to identify similar misconfigurations before they can be exploited in a production environment.
