CVE-2026-71147 in 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 network access via HTTP 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 and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hyperion Financial Management. CVSS 3.1 Base Score 4.2 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/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 significant security deficiency because it permits an unauthenticated attacker to compromise the system through network access via HTTP. The nature of this vulnerability is characterized by its difficulty to exploit, which serves as a partial mitigating factor against automated mass exploitation attempts. However, the requirement for human interaction from a person other than the attacker indicates that the attack vector likely involves social engineering or phishing tactics where a legitimate user must perform an action that triggers the malicious code path within the application logic.
From a technical perspective, this vulnerability aligns with CWE-79, which covers Cross-Site Scripting (XSS) vulnerabilities, particularly those involving stored or reflected scripts that require user interaction to execute. The presence of human interaction as a prerequisite suggests that the attacker may need to trick an authenticated administrator or data entry clerk into clicking a malicious link or submitting crafted input through the web interface. Once triggered, the flaw allows for unauthorized modifications to the database accessible by Oracle Hyperion Financial Management. This includes the ability to update, insert, or delete critical financial records, which directly impacts the integrity of the system's data. The manipulation of such sensitive financial data can lead to severe operational disruptions and compliance violations in enterprise environments where accurate reporting is paramount.
The impact assessment further reveals that this vulnerability also affects availability, albeit partially. Successful exploitation can result in a partial denial of service against Oracle Hyperion Financial Management services. This means that while the system may not be completely taken offline, its performance or responsiveness could be degraded to the point where business operations are hindered. The combination of integrity and availability impacts is reflected in the CVSS 3.1 Base Score of 4.2, which classifies this as a Medium severity issue. The vector string (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L) confirms that while no authentication is required to initiate the attack and it is network-accessible, the high complexity and requirement for user interaction limit its immediate threat level compared to critical remote code execution flaws.
In terms of industry standards mapping, this vulnerability exhibits characteristics consistent with ATT&CK technique T1059, Command and Scripting Interpreter, if the exploit involves executing arbitrary commands through injected scripts. It also relates to T1486, Data Encrypted for Impact, in scenarios where data integrity is compromised to disrupt operations, although here it is more directly linked to unauthorized data manipulation rather than encryption-based ransomware tactics. The lack of confidentiality impact suggests that sensitive data such as passwords or proprietary financial details are not immediately exfiltrated through this specific vector, focusing the risk squarely on operational integrity and availability.
Mitigation strategies must focus on both technical controls and user awareness training. Oracle should be consulted for any available patches or workarounds specifically addressing this security component flaw in version 11.2.25.0.000. Administrators should ensure that all web-facing components are hardened, potentially by implementing strict input validation and output encoding to neutralize script injection attempts. Additionally, deploying Web Application Firewalls can help detect and block malicious HTTP requests before they reach the application logic. Since human interaction is a key factor in exploitation, organizations must enforce rigorous security awareness programs to educate users about recognizing suspicious links or inputs that could trigger such vulnerabilities. Regular audits of user permissions and monitoring for anomalous data changes can also aid in early detection and response to potential exploitation attempts.
