CVE-2026-70903 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 network access via HTTPS 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 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 8.7 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/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 risk to organizations relying on this enterprise performance management platform for financial planning, budgeting, and reporting. The core technical issue involves an authentication or authorization bypass mechanism that allows low-privileged attackers with network access via HTTPS to compromise the system. Unlike many vulnerabilities that require complex exploitation chains or high-level privileges, this flaw is characterized by its ease of exploitability, meaning that even adversaries with minimal initial standing can leverage it to gain unauthorized control over critical application functions. The reliance on HTTPS as the attack vector indicates that the vulnerability persists despite encrypted communications, suggesting a logical error in how session tokens, credentials, or access controls are validated rather than a cryptographic weakness.
The operational impact of this vulnerability is severe due to its potential for scope change and high-impact outcomes. Successful exploitation does not merely affect the isolated instance of Oracle Hyperion Data Relationship Management but can significantly impact additional products within the broader enterprise ecosystem. This lateral movement capability arises because DRM often integrates with other Oracle Fusion Cloud applications or on-premise systems, allowing an attacker to pivot from a compromised data relationship management environment into adjacent financial or operational technology stacks. The primary consequences involve unauthorized creation, deletion, or modification of critical data, as well as complete access to all accessible data within the system. This encompasses sensitive financial records, strategic planning models, and proprietary business intelligence, leading to substantial integrity and confidentiality breaches that can disrupt organizational operations and violate regulatory compliance requirements such as SOX or GDPR.
From a classification perspective, this vulnerability aligns with CWE-287 Improper Authentication and CWE-948 Excessive Privileges, reflecting the failure of the system to correctly verify user identity or enforce role-based access controls. The presence of human interaction in the attack chain suggests that social engineering may be employed to trick users into performing actions that trigger the vulnerability, such as clicking a malicious link within an authenticated session or interacting with a crafted web request while logged in. This aligns with ATT&CK technique T1078 Valid Accounts and potentially T1566 Phishing if external actors are involved in initiating the exploit. The CVSS 3.1 base score of 8.7 underscores the critical nature of the flaw, driven by high impacts on confidentiality and integrity while maintaining a low attack complexity due to network accessibility and low privilege requirements for the initial attacker.
Mitigation strategies must prioritize immediate patching if Oracle has released an update addressing this specific version's security flaws. In the interim, organizations should implement strict access controls to limit who can interact with the DRM interface via HTTPS, ensuring that only essential personnel have login credentials. Network segmentation is crucial to isolate the Hyperion environment from other critical systems, thereby containing any potential lateral movement if a breach occurs. Additionally, deploying web application firewalls configured to detect anomalous authentication patterns or excessive data access requests can provide an additional layer of defense. Continuous monitoring for unusual data modifications or unauthorized access attempts within the DRM module is essential to identify exploitation in real-time and minimize the window of exposure before full remediation can be achieved.
