CVE-2026-70902 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. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Data Relationship Management accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Data Relationship Management accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/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 significant weakness in the application's authentication and authorization mechanisms, allowing for unauthorized manipulation or exfiltration of data by attackers who have already gained low-privileged access to the underlying infrastructure. The nature of this vulnerability suggests that while an attacker does not need high-level administrative privileges to initiate the exploit, they must first possess valid credentials or otherwise achieve logon capability on a system where Oracle Hyperion Data Relationship Management is deployed. This prerequisite highlights a critical dependency on perimeter security and internal network segmentation, as the initial foothold requires some level of legitimate access within the environment.
From a technical perspective, the vulnerability enables an attacker to compromise the integrity and confidentiality of the data managed by the application without requiring complex exploitation techniques or user interaction. The ease of exploitation indicates that the flaw may stem from improper validation of input parameters related to security contexts, insufficient checks on privilege escalation paths, or flawed logic in how access control lists are applied during runtime operations. Such weaknesses often arise when applications fail to properly enforce separation between different levels of privileged actions, allowing a user with standard permissions to execute functions reserved for administrators or other high-privilege roles. This type of flaw is frequently categorized under CWE-269 Improper Privilege Management or CWE-862 Missing Authorization, reflecting the core issue where the system fails to ensure that users only perform actions authorized for their current privilege level.
The operational impact of this vulnerability is severe due to its direct effect on data confidentiality and integrity. A successful exploitation allows an attacker to create, delete, or modify critical business data within Oracle Hyperion Data Relationship Management. This capability undermines the reliability of financial reporting and strategic planning processes that rely on accurate data inputs from the system. Furthermore, the ability to gain complete access to all accessible data poses a substantial risk for sensitive corporate information leakage. In enterprise environments where such systems are central to decision-making, unauthorized modifications can lead to significant financial losses, regulatory non-compliance, and reputational damage. The CVSS 3.1 base score of 7.1 underscores the high severity associated with these impacts, particularly given that both confidentiality and integrity metrics are rated as high while availability remains unaffected in this specific vector.
In terms of threat modeling, this vulnerability aligns with tactics observed in advanced persistent threats where attackers leverage low-privileged accounts to pivot through systems or escalate privileges laterally. It corresponds to the ATT&CK technique T1078 Valid Accounts, which describes adversaries using legitimate credentials to maintain access and move within a network undetected. By exploiting weaknesses in how these valid but lower-level accounts interact with security-critical components like data relationship management tools, attackers can establish a persistent presence or extract valuable intellectual property before detection mechanisms trigger alerts for more overtly malicious activities.
Mitigation strategies should focus on both immediate remediation and long-term architectural improvements. The primary action is to apply the latest security patches provided by Oracle that address this specific flaw in version 11.2.25.0.000 or later releases where applicable. Organizations must ensure their patch management processes are rigorous enough to deploy these updates promptly across all affected instances. Additionally, implementing strict network segmentation can limit the blast radius of such vulnerabilities by ensuring that systems hosting Oracle Hyperion Data Relationship Management are isolated from general user networks and only accessible through secure, monitored channels. Enforcing multi-factor authentication for all accounts with access to the infrastructure adds an additional layer of defense against credential theft or misuse. Regular audits of user permissions should also be conducted to ensure adherence to the principle of least privilege, minimizing the number of users who have logon capabilities on systems running critical enterprise applications.
