CVE-2026-70895 in Hyperion Data Relationship Management
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Hyperion Data Relationship Management product of Oracle Hyperion (component: Access and security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Hyperion Data Relationship Management executes to compromise Oracle Hyperion Data Relationship Management. 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. CVSS 3.1 Base Score 6.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).

The identified vulnerability resides within the Access and security component of Oracle Hyperion Data Relationship Management, specifically affecting version 11.2.25.0.000. This flaw represents a critical weakness in how the application handles authentication and authorization processes for users who have already gained initial access to the underlying infrastructure. The core technical issue involves an insufficient mechanism for validating user privileges during specific operations within the Data Relationship Management environment. While the vulnerability is technically located within this specific product, its exploitation can lead to significant scope changes, potentially impacting additional products that rely on or are integrated with Oracle Hyperion systems. This lateral impact capability underscores the interconnected nature of enterprise application suites and highlights how a localized security failure in one module can cascade into broader organizational risk.
From an operational perspective, the vulnerability is characterized by its exploitability for low-privileged attackers who possess valid logon credentials to the infrastructure hosting the vulnerable software. The attacker does not require complex preconditions or user interaction, such as clicking malicious links, making the attack vector straightforward and highly feasible in environments where internal network segmentation is weak or where users have broad access rights. Once exploited, the vulnerability allows for unauthorized access to critical data stored within the Data Relationship Management system. In severe cases, it grants complete access to all accessible data managed by the application. This level of compromise directly impacts the confidentiality integrity and availability principles of information security, as sensitive financial models, relationships, and strategic planning data can be exfiltrated or manipulated without detection.
The severity of this vulnerability is quantified by a CVSS 3.1 Base Score of 6.5, primarily driven by high impact on confidentiality with no direct impact on integrity or availability in the base score calculation. The vector string AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N indicates that while the attack requires local network access and low privileges, it is easy to execute and results in high confidentiality loss due to scope change effects. This aligns with Common Weakness Enumeration categories such as CWE-269 Improper Privilege Management or CWE-862 Missing Authorization, depending on whether the flaw stems from a failure to enforce role-based access controls or improper handling of session tokens. Furthermore, this behavior maps to MITRE ATT&CK techniques related to Credential Access and Lateral Movement, specifically where an attacker leverages existing valid credentials to escalate privileges or move laterally across integrated systems within the enterprise architecture.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. The primary action is to apply the latest security patches provided by Oracle for version 11.2.25.0.000 as soon as they are available in official release channels. In addition to patching, organizations should enforce strict network segmentation to limit access to the infrastructure hosting Oracle Hyperion Data Relationship Management to only those systems and users that absolutely require it. Implementing multi-factor authentication for all administrative accounts can significantly raise the barrier for attackers attempting to leverage low-privileged credentials. Furthermore, continuous monitoring of user activity logs within the application is essential to detect anomalous behavior indicative of privilege escalation attempts. Regular audits of access control lists and role definitions will help ensure that users operate under the principle of least privilege, reducing the potential blast radius if a vulnerability such as this one were to be exploited in the future.
