CVE-2026-70919 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. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle Hyperion Financial Management executes to compromise Oracle Hyperion Financial Management. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Hyperion Financial Management accessible data. CVSS 3.1 Base Score 2.5 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N).

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 is classified as a difficult-to-exploit security issue that impacts the integrity of the application's data stores. The core technical nature of this vulnerability involves an authorization bypass or logic error within the web interface or API layer, which allows for unauthorized manipulation of financial records despite the presence of authentication mechanisms. While the attacker must first establish a valid logon session to the infrastructure hosting Oracle Hyperion Financial Management, the subsequent exploitation does not require elevated privileges but rather relies on specific user interactions that are not properly validated by the backend security controls.
From an operational perspective, this vulnerability poses a significant risk to organizations relying on Oracle Hyperion for critical financial reporting and analysis. The successful exploitation of this flaw enables an unauthenticated attacker who has gained initial access to the infrastructure to perform unauthorized updates, inserts, or deletes against accessible data within the application. This capability directly compromises the integrity of financial records, which can lead to inaccurate reporting, regulatory non-compliance, and potential fraud if malicious actors alter transactional data without detection. The impact is strictly limited to integrity as indicated by the CVSS vector, meaning confidentiality and availability are not directly affected in this specific attack scenario, but the trustworthiness of the financial system is severely undermined.
The exploitation complexity for this vulnerability is rated as high due to two primary factors: a high attack complexity requirement and the necessity for human interaction. The attacker must have network access to log into the Oracle Hyperion Financial Management environment, which typically implies they are inside the corporate perimeter or have compromised an internal account. Furthermore, the requirement for user interaction suggests that the exploit may involve social engineering tactics, such as tricking a legitimate user into clicking a malicious link or submitting crafted input through the application interface. This dependency on human action significantly reduces the likelihood of automated remote exploitation but increases the risk in environments with weak security awareness training among financial staff and administrators.
In terms of industry standard classifications, this vulnerability aligns with CWE-269, which addresses Improper Privilege Management, as it allows a user to perform actions beyond their intended scope through flawed validation logic. It also relates to CWE-74, Injection, if the unauthorized data modifications are achieved via crafted input that bypasses sanitization checks within the application layer. From an offensive security framework perspective, this behavior is consistent with MITRE ATT&CK technique T1059, Command and Scripting Interpreter, or more specifically T1136, Create Account, depending on how the initial access was gained, but the exploitation phase maps to T1213, Data from Information Repositories, where the attacker extracts or modifies data for malicious purposes. The low base score of 2.5 reflects the limited scope and high barriers to entry, yet it remains critical due to the sensitivity of financial data involved.
Mitigation strategies should focus on both technical controls and procedural safeguards. Organizations running Oracle Hyperion Financial Management version 11.2.25.0.000 or affected versions must apply the latest security patches provided by Oracle as soon as they are available, ensuring that all known flaws in the Security component are addressed. Access control policies should be reviewed to enforce strict least-privilege principles, ensuring that users only have access to data necessary for their specific roles. Additionally, implementing multi-factor authentication can reduce the risk of initial infrastructure compromise, while network segmentation can limit lateral movement if an attacker gains a foothold on the hosting server. Security awareness training is also crucial to mitigate the human interaction aspect, educating staff to recognize and report suspicious requests or unusual application behavior that could indicate exploitation attempts. Regular audits of financial data integrity should be conducted to detect any unauthorized modifications promptly.
