CVE-2026-70901 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 unauthenticated 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. 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 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/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 critical weakness in the application's authentication and authorization mechanisms, allowing for unauthorized access to sensitive data structures managed by the platform. The core technical issue stems from insufficient validation or enforcement of security controls during HTTP-based interactions with the server. While the vulnerability is easily exploitable due to low attack complexity and network accessibility, it contains a specific prerequisite that requires human interaction from a user other than the attacker. This characteristic suggests that the exploit likely involves social engineering tactics, such as phishing or malicious link injection, where an unsuspecting authenticated user must perform an action that triggers the vulnerable code path. The presence of this requirement indicates that the vulnerability may involve Cross-Site Request Forgery patterns or similar mechanisms where a victim's session is abused to execute unintended commands within the context of their privileges.
From a technical perspective, the flaw allows unauthenticated attackers who can manipulate user interactions via HTTP to compromise the integrity and confidentiality of the system. The CVSS 3.1 base score of 8.1 reflects high severity, driven primarily by significant impacts on Confidentiality and Integrity while Availability remains unaffected. This scoring aligns with CWE-20 Improper Input Validation or potentially CWE-94 Code Injection if the attack vector involves manipulating input to alter system behavior. Furthermore, the requirement for human interaction maps directly to ATT&CK technique T1566 Phishing, where attackers rely on user actions to bypass technical controls. The attacker does not need prior authentication credentials but must trick a legitimate user into initiating requests that exploit the security gap in how the application processes these inputs. This creates a scenario where an external actor can leverage trusted sessions to perform operations they are otherwise denied access to.
The operational impact of this vulnerability is severe, as successful exploitation grants unauthorized creation, deletion, or modification capabilities over critical data within Oracle Hyperion Data Relationship Management. Since DRM handles complex financial and business relationships, the ability to alter or delete such data can lead to significant financial discrepancies, reporting errors, and regulatory compliance failures. Additionally, attackers may gain complete access to all accessible data in the system, leading to substantial confidentiality breaches involving sensitive corporate information, strategic plans, or proprietary algorithms. The lack of availability impact suggests that while data integrity is compromised, the service itself remains operational, which might allow malicious changes to persist undetected for extended periods before causing visible disruptions. This persistence increases the risk of long-term damage and makes forensic analysis more challenging as logs may not immediately reflect anomalous behavior if the attacker mimics legitimate user actions closely enough.
Mitigation strategies must focus on both immediate technical controls and broader security hygiene improvements. Oracle should apply the latest available patches or updates that address this specific flaw in the Access and security component for version 11.2.25.0.000. In environments where patching is not immediately feasible, network-level mitigations such as Web Application Firewalls can be configured to detect and block suspicious HTTP patterns associated with CSRF attacks or unusual data manipulation requests. Implementing strict Content Security Policy headers and ensuring that session tokens are properly validated against origin domains can also reduce the risk of exploitation. Furthermore, organizations should enforce multi-factor authentication for all users accessing the DRM application to add an additional layer of verification beyond standard credentials. Regular security awareness training is essential to mitigate the human interaction aspect, educating staff on recognizing phishing attempts and suspicious links that could trigger this vulnerability. Continuous monitoring of audit logs for anomalous data changes can help in early detection and response to potential exploitation attempts.
