CVE-2026-87156 in Product Hub
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Product Hub 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 Product Hub. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Product Hub accessible data as well as unauthorized update, insert or delete access to some of Oracle Product Hub accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N).

The identified vulnerability resides within the Internal Operations component of Oracle Product Hub, a core module of the Oracle E-Business Suite ecosystem. This security flaw affects supported software versions ranging from 12.2.3 through 12.2.15. The nature of this defect allows for exploitation by an attacker who possesses low-level privileges and has network access via HTTP to the affected system. Unlike vulnerabilities that require complex interaction or user deception, this issue is characterized as easily exploitable because it does not necessitate any user interface involvement from a victim, thereby lowering the barrier for successful attack execution significantly.
From a technical perspective, the flaw enables unauthorized manipulation of data within the Oracle Product Hub environment. Successful exploitation grants an attacker the ability to access critical confidential information that should be restricted based on role-based permissions. Furthermore, the vulnerability compromises system integrity by allowing unauthorized updates, insertions, or deletions of accessible data. This dual impact on both confidentiality and integrity highlights a fundamental failure in access control mechanisms within the internal operations layer, where privilege escalation is not required to achieve significant malicious outcomes.
The operational impact of this vulnerability is substantial for organizations relying on Oracle E-Business Suite for supply chain management and product lifecycle activities. An attacker could exfiltrate sensitive business data, leading to competitive disadvantage or regulatory non-compliance depending on the nature of the exposed information. Additionally, the ability to modify or delete records can disrupt business operations, cause financial loss through erroneous transactions, and corrupt master data essential for downstream systems. The CVSS 3.1 base score of 7.1 reflects this high severity, driven primarily by the High impact on confidentiality and Low impact on integrity, with no direct impact on availability in the standard scoring model, although operational disruption remains a practical risk due to data corruption.
In terms of industry classification standards, this vulnerability aligns closely with CWE-269 Improper Privilege Management or potentially CWE-862 Missing Authorization if the issue stems from insufficient checks before granting access to specific resources. The attack vector corresponds to ATT&CK technique T1078 Valid Accounts, as it leverages low privileged credentials that are already present within the network perimeter. It also relates to data exfiltration techniques such as T1530 Data from Local System or T1567 Exfiltration Over Web Service if the attacker uses HTTP channels to send stolen data externally. The lack of user interaction places it in categories associated with automated exploitation tools that target web application vulnerabilities without social engineering components.
Mitigation strategies must prioritize immediate patching by Oracle, as this is a known defect affecting specific version ranges within the E-Business Suite product line. Organizations should apply the latest security patches provided by Oracle for their respective supported versions to close the underlying code flaws responsible for these access control failures. In environments where patching cannot be implemented immediately due to operational constraints or testing requirements, network segmentation and strict firewall rules should be enforced to restrict HTTP access to the Internal Operations component only from trusted application servers or management networks. Additionally, implementing Web Application Firewalls with robust rule sets can help detect and block exploitation attempts that target these specific endpoints by analyzing request patterns for anomalies indicative of unauthorized data manipulation or exfiltration efforts.
