CVE-2026-87132
Summary
by MITRE • 09/15/2026
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 involves an authentication or authorization bypass mechanism that allows low-privileged attackers with network access via HTTP to compromise the system. Unlike high-severity vulnerabilities that can be exploited automatically, this specific weakness requires human interaction from a user other than the attacker. This characteristic suggests the vulnerability likely leverages social engineering tactics, such as phishing or malicious link injection, where an unsuspecting authenticated user is tricked into performing an action that triggers the exploit within their active session context.
From a technical perspective, the requirement for human interaction indicates that the attack vector relies on manipulating legitimate users to execute unintended operations or disclose sensitive information while logged in with elevated privileges relative to the attacker's current role. Although the initial access point is limited by the need for user engagement, the subsequent exploitation allows the low-privileged attacker to escalate their influence within the application environment. The vulnerability enables unauthorized access to critical data and can lead to complete access to all Oracle Hyperion Data Relationship Management accessible data stored on the server. Furthermore, it permits unauthorized updates, inserts, or deletes against a subset of this data, thereby compromising both confidentiality and integrity aspects of the system's security posture.
The operational impact of this vulnerability extends beyond the immediate application due to its potential for scope change. While the flaw is technically located within Oracle Hyperion Data Relationship Management, successful exploitation can significantly impact additional products connected to or integrated with the platform. This lateral movement capability means that compromising one component could serve as a foothold for attacking other systems in the enterprise network, particularly those sharing authentication directories or data repositories. The CVSS 3.1 Base Score of 7.6 reflects this high severity, driven primarily by the High impact on Confidentiality and Low impact on Integrity, with no direct 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) confirms that while the attack complexity is low for a user who interacts with it, the privilege requirement remains at Low, and the scope changes from User to System-level impact upon successful exploitation.
In terms of industry standard classifications, this vulnerability aligns with CWE-200, which covers Exposure of Sensitive Information to an Unauthorized Actor, as well as CWE-798, involving Use of Hard-coded Credentials if applicable in the authentication bypass mechanism, or potentially CWE-352 for Cross-Site Request Forgery given the human interaction requirement. From a tactical standpoint, this aligns with MITRE ATT&CK techniques such as T1078 Valid Accounts, where attackers leverage legitimate credentials obtained through social engineering, and T1566 Phishing, which facilitates the initial user interaction required to trigger the flaw. The scope change aspect also relates to lateral movement strategies described in frameworks like D3FEND or MITRE ATT&CK's Initial Access and Persistence tactics when combined with other post-exploitation tools.
Mitigation efforts must focus on both technical controls and organizational policies. Administrators should immediately apply the latest security patches provided by Oracle for version 11.2.26.0.000 to close the underlying code flaw. In addition to patching, implementing strict access control lists and role-based access management can limit the blast radius if a low-privileged account is compromised. Security teams should enforce multi-factor authentication across all Hyperion components to mitigate the risk of credential theft that often precedes such exploits. Network segmentation strategies should be reviewed to ensure that even if an attacker gains initial foothold via HTTP, they cannot easily pivot to other critical systems or databases connected to the Hyperion environment. User awareness training is also crucial, as educating employees about phishing attempts and suspicious links can significantly reduce the success rate of attacks requiring human interaction. Regular auditing of user activities and monitoring for anomalous data access patterns will help detect potential exploitation attempts early in the kill chain.
