CVE-2026-70934 in Hyperion Financial Management
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Hyperion Financial Management product of Oracle Hyperion (component: 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 Financial Management. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hyperion Financial Management accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hyperion Financial Management. CVSS 3.1 Base Score 7.1 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L).

The identified vulnerability resides within the Security component of Oracle Hyperion Financial Management, specifically affecting version 11.2.25.0.000 and potentially other supported releases in that lineage. This flaw represents a critical security deficiency that undermines the integrity of access controls governing the financial management platform. The nature of this weakness allows for exploitation by an attacker who possesses only low-level privileges, significantly lowering the barrier to entry compared to vulnerabilities requiring administrative or high-privileged accounts. Such attackers can leverage network connectivity via the HTTP protocol to interact with the vulnerable service endpoints, indicating that the attack vector is remote and does not require physical access or local system interaction on the target machine.
From a technical perspective, this vulnerability aligns closely with CWE-284, which describes Improper Access Control, as well as CWE-798, involving the use of hardcoded credentials or insufficient authentication checks that allow unauthorized entities to bypass security mechanisms. The exploitation path likely involves manipulating HTTP requests to exploit logic flaws in how session tokens are validated or how role-based access control lists are processed by the application server. Because the vulnerability is easily exploitable and requires no user interaction (UI:N), it poses a severe risk to organizations relying on this software for sensitive financial data processing. The absence of complex preconditions means that automated scanning tools could potentially detect and exploit this weakness if exposed to untrusted networks, although standard security practices should restrict such exposure.
The operational impact of successful exploitation is substantial, primarily targeting the confidentiality and availability aspects of the CIA triad, as reflected in the CVSS 3.1 base score of 7.1. The primary consequence is unauthorized access to critical financial data, which could include sensitive balance sheets, profit and loss statements, budget forecasts, and audit trails. This level of compromise allows an attacker to exfiltrate proprietary information that could be used for competitive intelligence or fraud. Furthermore, the vulnerability enables a partial denial of service condition. While this may not result in a complete system crash, it can degrade performance or render specific modules inaccessible, disrupting financial reporting cycles and operational continuity within the organization.
In terms of threat modeling, this scenario maps to MITRE ATT&CK techniques such as T1078, Valid Accounts, where an attacker uses legitimate credentials with insufficient privileges to gain access, potentially escalating through lateral movement if other systems are similarly misconfigured. It also relates to T1499, Endpoint Denial of Service, due to the partial DOS capability. The combination of low privilege requirement and network accessibility makes this a high-priority issue for security operations teams monitoring Oracle Hyperion deployments.
To mitigate these risks, immediate action is required from system administrators and security architects. The primary remediation step involves applying the latest available patches or updates provided by Oracle that address this specific security flaw in version 11.2.25.0.000. Organizations should verify their patch levels against Oracle Critical Patch Update advisories to ensure they are running a fixed release. Additionally, network segmentation strategies should be reviewed to ensure that the Hyperion Financial Management servers are not directly accessible from untrusted networks via HTTP. Implementing an application firewall or reverse proxy with strict access control lists can help restrict entry points and inspect traffic for anomalous patterns indicative of exploitation attempts. Regular vulnerability assessments focused on web applications and financial systems will also aid in detecting similar misconfigurations before they can be leveraged by adversaries.
