CVE-2026-71149 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 low privileged 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 as well as unauthorized read access to a subset of 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 4.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L).

The identified vulnerability resides within the Security component of Oracle Hyperion Financial Management version 11.2.25.0.000, representing a significant risk to organizations relying on this enterprise performance management platform for critical financial data processing and reporting. This flaw is classified as an access control issue where the application fails to properly enforce security policies regarding user permissions and session handling during specific interactions with the system's core modules. The vulnerability allows low-privileged attackers who have already obtained valid logon credentials to the infrastructure hosting Oracle Hyperion Financial Management to compromise the integrity, confidentiality, or availability of the application data. This scenario typically involves an insider threat or a compromised account from within the network perimeter, as the attack vector is local rather than remote over the internet.
From a technical perspective, the flaw stems from insufficient validation of user roles and permissions when processing specific requests that modify or retrieve financial records. While standard access controls prevent unauthorized users from accessing sensitive data under normal circumstances, this vulnerability introduces an edge case where privilege escalation occurs through manipulated input parameters or session state exploitation. The attacker leverages their existing low-level privileges to bypass intended restrictions, effectively gaining higher levels of access than originally granted by the system administrator. This behavior aligns with CWE-269 Improper Privilege Management and CWE-862 Missing Authorization, indicating that the application logic does not consistently verify whether a user has the right to perform an action on a specific resource based on their assigned role.
The operational impact of this vulnerability is multifaceted, affecting all three pillars of the CIA triad: confidentiality, integrity, and availability. Successful exploitation can lead to unauthorized read access to a subset of accessible data, exposing sensitive financial information such as budgets, forecasts, or actuals to individuals who should not have visibility into those records. Furthermore, attackers can perform unauthorized updates, inserts, or deletes against database entries, which compromises the accuracy and reliability of financial reports used for executive decision-making and regulatory compliance. Additionally, the vulnerability enables a partial denial of service condition, potentially disrupting business operations by rendering certain modules or functions unavailable to legitimate users during periods of exploitation attempts.
The complexity of exploiting this vulnerability is rated as high due to several mitigating factors inherent in its design requirements. First, the attacker must possess valid logon credentials for an account with low-level privileges on the infrastructure where Oracle Hyperion Financial Management executes. Second, successful exploitation requires human interaction from a person other than the primary attacker, suggesting that social engineering or phishing tactics may be necessary to trigger the vulnerable code path within the application interface. This requirement significantly raises the barrier to entry for remote attackers who lack physical or internal network access and valid credentials, thereby limiting the threat landscape primarily to insider threats or compromised accounts within trusted networks.
The severity of this vulnerability is quantified by a CVSS 3.1 Base Score of 4.2, classified as Medium risk. The vector string (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L) reflects the local attack vector, high complexity, low required privileges, and user interaction requirement. While not immediately critical in terms of remote exploitation potential, the combination of data exfiltration capabilities with integrity violations poses a substantial risk to financial accuracy and regulatory adherence. Organizations must treat this as a serious concern given that Oracle Hyperion Financial Management often serves as the single source of truth for corporate financial planning and analysis processes.
To mitigate these risks, organizations should implement strict access control policies ensuring that low-privileged accounts have minimal exposure to sensitive modules within the application. Principle of least privilege should be rigorously enforced across all user roles, with regular audits conducted to verify that no unnecessary permissions are granted. Additionally, multi-factor authentication should be mandated for all logon attempts to reduce the likelihood of credential compromise leading to exploitation. Monitoring and logging mechanisms must be enhanced to detect anomalous behavior patterns indicative of unauthorized data access or modification attempts, allowing security teams to respond swiftly to potential incidents.
From a threat intelligence perspective, this vulnerability maps to MITRE ATT&CK techniques related to Privilege Escalation and Collection via Local File Access or Application Layer Protocol manipulation depending on the specific exploit mechanism used by attackers. Security operations centers should update their detection rules to flag unusual activity patterns associated with low-privileged users accessing high-value financial data sets outside of normal business hours or typical usage profiles. Patching remains the most effective long-term solution, and organizations are strongly advised to apply the latest security updates provided by Oracle as soon as they become available for version 11.2.25.0.000 and subsequent releases that address this specific flaw in the Security component.
