CVE-2026-87137 in Hyperion Data Relationship Management
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Hyperion Data Relationship Management product of Oracle Hyperion (component: Access and security). The supported version that is affected is 11.2.26.0.000. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Data Relationship Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hyperion Data Relationship Management, 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 Hyperion Data Relationship Management accessible data as well as unauthorized update, insert or delete access to some of Oracle Hyperion Data Relationship Management accessible data. CVSS 3.1 Base Score 7.6 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N).

The identified vulnerability resides within the Access and security component of Oracle Hyperion Data Relationship Management, specifically affecting version 11.2.26.0.000. This flaw represents a significant risk to organizations relying on this enterprise performance management platform for financial reporting and data consolidation. The core technical issue stems from an insufficient validation or authorization check within the HTTP-based interface of the application. While the vulnerability is localized to Oracle Hyperion Data Relationship Management, its exploitation can lead to a scope change where additional products are impacted due to shared underlying infrastructure or integrated data models. This characteristic underscores the interconnected nature of modern enterprise software suites and how a weakness in one module can cascade into broader system compromise.
From an operational perspective, this vulnerability is classified as easily exploitable by low-privileged attackers who have network access via HTTP. The attack vector requires human interaction from a user other than the attacker, indicating that social engineering or phishing tactics may be necessary to trigger the exploit. Once triggered, however, the consequences are severe and multifaceted. Successful exploitation allows an unauthorized actor to gain complete access to all data accessible by Oracle Hyperion Data Relationship Management. This includes sensitive financial records, strategic planning documents, and proprietary business intelligence. The impact extends beyond mere confidentiality breaches; it also compromises integrity through the ability to perform unauthorized updates, inserts, or deletes on critical datasets. Such actions could lead to corrupted financial reports, manipulated budgets, or deleted audit trails, severely undermining the reliability of organizational decision-making processes.
The severity of this vulnerability is quantified by a CVSS 3.1 Base Score of 7.6, reflecting high impacts on confidentiality and low impacts on integrity, with no impact on availability. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N) highlights that while the attack requires user interaction and local privileges, the resulting scope change amplifies the risk significantly. In terms of industry standards, this vulnerability aligns with CWE-269 Improper Privilege Management or potentially CWE-798 if it involves hardcoded credentials, though the description emphasizes access control failures. From a tactical standpoint within the MITRE ATT&CK framework, this scenario maps to techniques involving Initial Access through user interaction and subsequent Lateral Movement or Data Exfiltration depending on how the compromised data is utilized. The scope change aspect also relates to T1534 Internal Spearphishing if internal users are tricked into triggering the exploit against other connected systems.
Mitigation strategies must address both immediate remediation and long-term security posture improvements. Oracle should be consulted for the latest patches or updates that resolve this specific access control flaw in version 11.2.26.0.000. In the interim, organizations should restrict HTTP access to the application by enforcing HTTPS with strong certificate validation to prevent man-in-the-middle attacks and ensure encrypted transmission of sensitive data. Network segmentation is critical; placing Oracle Hyperion Data Relationship Management in a restricted DMZ or VLAN limits exposure to low-privileged network users who might attempt exploitation. Additionally, implementing strict role-based access control ensures that even if the vulnerability is triggered, the attacker’s privileges remain limited until further lateral movement occurs. User awareness training should be enhanced to reduce the success rate of social engineering attacks that require human interaction for exploit delivery. Regular audits of user permissions and monitoring for anomalous data modification patterns can also help detect potential exploitation attempts early in the kill chain.
