CVE-2026-70882 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 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 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 reporting and data consolidation. The core technical issue involves an improper validation or authorization mechanism within the HTTP-based interface that processes user requests. While the vulnerability is localized to Oracle Hyperion Data Relationship Management, its exploitation can lead to a scope change, meaning the impact extends beyond the immediate application layer to potentially compromise underlying systems or integrated products connected to the platform. This lateral movement capability amplifies the severity of the flaw, as it allows an attacker to pivot from a single compromised service to broader organizational assets.
The exploitability profile indicates that while the attack vector is network-based via HTTP and requires only low-privileged access for the initial foothold, it necessitates human interaction. This characteristic aligns with social engineering vectors where an attacker might trick a legitimate user into performing an action, such as clicking a malicious link or submitting crafted input through the web interface. Once this interaction occurs, the vulnerability allows for unauthorized creation, deletion, or modification of critical data within the Data Relationship Management environment. The impact on confidentiality is equally severe, granting attackers complete access to all accessible data managed by the system. This dual threat to both integrity and confidentiality underscores the high severity rating assigned to this flaw.
From a classification perspective, this vulnerability maps closely to CWE-269, which addresses Improper Privilege Management, as it allows low-privileged users to perform actions reserved for higher-level administrators or data owners. Furthermore, the requirement for human interaction places it within the realm of social engineering attacks often categorized under ATT&CK technique T1534, specifically Internal Spearphishing if the attack originates from inside the network, or potentially T1078 if valid credentials are abused following initial access. The ability to modify and delete data also relates to CWE-269 regarding insufficient privileges for specific operations, while the unauthorized access aligns with CWE-200, which covers Exposure of Sensitive Information to an Unauthorized Actor.
The operational impact of this vulnerability is substantial due to the nature of Data Relationship Management systems. These platforms typically house sensitive financial data, strategic planning models, and consolidated reports that are critical for executive decision-making and regulatory compliance. An attacker gaining unauthorized access can alter financial figures, delete essential relationships between entities, or exfiltrate proprietary business intelligence. The scope change implication means that if the compromised system interacts with other Oracle products or external databases, those systems may also be jeopardized, leading to a cascading failure of security controls across multiple applications. This interconnected risk highlights the importance of treating this vulnerability not as an isolated incident but as a potential gateway for broader infrastructure compromise.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. The primary defense is applying the latest security patches provided by Oracle, which address the specific flaws in the access control logic within version 11.2.25.0.000. Organizations should prioritize patching this component to eliminate the root cause of the privilege escalation or authorization bypass. In addition to patching, implementing strict network segmentation can limit the blast radius if an attacker does gain initial low-privileged access. Restricting HTTP traffic to only necessary endpoints and enforcing multi-factor authentication for all user accounts adds layers of defense that mitigate the risk of successful exploitation even if human interaction is induced by social engineering tactics.
Security teams should also enhance monitoring capabilities to detect anomalous activities associated with this vulnerability. Since the attack requires a victim's action, looking for unusual patterns in HTTP request logs or unexpected data modifications can help identify attempted exploits in real-time. Implementing Web Application Firewalls configured to recognize and block common exploitation techniques related to privilege escalation and unauthorized data access can provide an additional layer of protection. Regular audits of user permissions ensure that low-privileged accounts do not have excessive rights, reducing the potential impact if a vulnerability is exploited. By combining timely patching with robust monitoring and strict access controls, organizations can effectively neutralize this threat and maintain the integrity and confidentiality of their critical financial data infrastructure.
