CVE-2026-83089 in Alert
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Alert 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 Alert. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Alert accessible data as well as unauthorized access to critical data or complete access to all Oracle Alert accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the Internal Operations component of Oracle Alert, a module integral to Oracle E-Business Suite versions 12.2.3 through 12.2.15. This security flaw represents a significant risk vector for organizations relying on these specific releases of the enterprise resource planning platform. The core issue stems from an insufficient access control mechanism within the application logic that processes HTTP requests directed at internal operational endpoints. Because the vulnerability is easily exploitable and requires only low-privileged credentials, it effectively lowers the barrier for entry for attackers who have already gained a foothold in the network perimeter or obtained valid user accounts with minimal privileges. The attack vector is explicitly defined as network-based via HTTP, indicating that remote exploitation is feasible without requiring physical access to the target systems or complex social engineering tactics beyond initial credential acquisition.
From a technical perspective, the flaw allows an attacker to manipulate critical data structures and operational parameters within Oracle Alert. Successful exploitation leads to unauthorized creation, deletion, or modification of sensitive information managed by the alerting subsystem. This capability directly impacts both the confidentiality and integrity aspects of the security triad. An adversary can exfiltrate confidential business logic, customer records, or financial data stored in accessible tables, while simultaneously altering configurations or triggering false alerts that could disrupt operational workflows. The absence of an availability impact suggests that the vulnerability is primarily used for data theft or tampering rather than service disruption, although the integrity loss may indirectly cause operational inefficiencies if critical alert rules are corrupted.
The severity of this vulnerability is quantified by a CVSS 3.1 Base Score of 8.1, classified as High. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) highlights that the attack requires no user interaction and has low complexity, but demands local network access and low privileges. This profile aligns with common post-exploitation scenarios where an attacker leverages compromised credentials from a less-privileged account to pivot into more sensitive areas of the application. In terms of industry standards, this vulnerability maps closely to CWE-269 Improper Privilege Management and CWE-862 Missing Authorization. Furthermore, within the MITRE ATT&CK framework, such behavior is indicative of techniques associated with Lateral Movement or Data Exfiltration via Application Layer Protocols, specifically leveraging existing valid credentials to access resources that should be restricted based on role-based access controls.
Mitigation strategies must prioritize immediate patching and rigorous access control reviews. Oracle has likely released security patches for the affected versions; therefore, applying the latest critical patch updates is the primary remediation step. Organizations running unsupported or unpatched instances of E-Business Suite 12.2.x should accelerate their upgrade timelines to mitigate this risk. In addition to patching, implementing strict network segmentation can limit exposure by ensuring that only authorized application servers and management consoles have HTTP access to Oracle Alert components. Role-based access control policies must be audited to ensure that low-privileged users do not possess unnecessary permissions over internal operations modules. Regular vulnerability scanning focused on web application endpoints and continuous monitoring of audit logs for anomalous data modification patterns will further enhance the security posture against this specific threat vector.
