CVE-2026-70784 in Hyperion Financial Reporting
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Hyperion Financial Reporting product of Oracle Hyperion (component: Server). The supported version that is affected is 11.2.25.0.000. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Hyperion Financial Reporting executes to compromise Oracle Hyperion Financial Reporting. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Financial Reporting accessible data as well as unauthorized read access to a subset of Oracle Hyperion Financial Reporting accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:N).

Analysis

The identified vulnerability resides within the Oracle Hyperion Financial Reporting product, specifically affecting the Server component in version 11.2.25.0.000 and potentially other supported releases. This security flaw is classified as a difficult-to-exploit issue that requires an attacker to have low-privileged access with valid logon credentials to the infrastructure hosting the Oracle Hyperion Financial Reporting service. The nature of this vulnerability suggests a failure in proper authorization checks or input validation mechanisms within the server-side processing logic, allowing authenticated users with minimal privileges to perform actions beyond their intended scope. This type of flaw is commonly associated with CWE-269 Improper Privilege Management or CWE-862 Missing Authorization, where the application fails to enforce appropriate access controls for specific resources or functions based on the user's role and permissions.
The operational impact of a successful exploitation is significant regarding data integrity and confidentiality, while availability remains unaffected according to the provided metrics. An attacker who successfully exploits this vulnerability can achieve unauthorized creation, deletion, or modification of critical data within the Oracle Hyperion Financial Reporting environment. Furthermore, they may gain unauthorized read access to a subset of accessible data. This capability allows for substantial manipulation of financial reports and underlying datasets, which could lead to inaccurate financial reporting, regulatory non-compliance, and potential fraud if left undetected. The ability to modify critical data poses a direct threat to the integrity of business operations that rely on accurate financial information generated by this system.
From an offensive security perspective, this vulnerability aligns with ATT&CK technique T1078 Valid Accounts, as it requires legitimate credentials to execute. Once authenticated, the attacker leverages privilege escalation or access control bypasses to manipulate data, which corresponds to techniques such as T1565 Data Manipulation or T1499 Endpoint Denial of Service if deletion is involved, though in this context, the primary concern is integrity compromise rather than service disruption. The high complexity and low attack vector indicate that while the vulnerability is serious, it cannot be exploited remotely without prior network access and valid user credentials, limiting its exploitability to insider threats or compromised accounts within the internal network perimeter.
Mitigation strategies should focus on strict adherence to the principle of least privilege and robust monitoring of administrative activities. Organizations running this version must apply the latest security patches provided by Oracle as soon as they are available for the 11.2.25.0.000 release or later supported versions. In addition to patching, it is crucial to review user access rights within the Hyperion environment to ensure that low-privileged accounts do not possess unnecessary write or delete permissions on critical financial data sets. Implementing multi-factor authentication for all administrative and high-risk user accounts can further reduce the risk of credential compromise leading to exploitation. Continuous monitoring of system logs for anomalous activities, such as unexpected modifications to report structures or unauthorized access attempts by low-privileged users, will aid in early detection and response to potential exploitation attempts.
