CVE-2026-87250 in Hyperion Financial Management
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Hyperion Financial Management product of Oracle Hyperion (component: Security). The supported version that is affected is 11.2.26.0.000. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Financial Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hyperion Financial Management, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hyperion Financial Management accessible data as well as unauthorized update, insert or delete access to some of Oracle Hyperion Financial Management accessible data. CVSS 3.1 Base Score 7.6 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N).

The identified vulnerability resides within the Security component of Oracle Hyperion Financial Management, specifically affecting version 11.2.26.0.000 and potentially other supported releases in the suite. This flaw represents a significant security deficiency that allows for unauthorized access to sensitive financial data and manipulation of critical records. The nature of this vulnerability is characterized by its ease of exploitation despite requiring low-privileged attacker credentials, which lowers the barrier to entry for malicious actors who may have gained initial foothold within an organization's network or through phishing campaigns targeting employees with limited system privileges.
From a technical perspective, the flaw enables attackers to compromise the integrity and confidentiality of the Oracle Hyperion Financial Management application via HTTP-based interactions. The vulnerability is classified under CWE-200 as an Information Exposure issue, where sensitive data becomes accessible without proper authorization controls. Furthermore, it aligns with ATT&CK technique T1530, Data from Local System, indicating that once exploited, the attacker can exfiltrate or view stored information that should remain restricted to authorized personnel only. The presence of this flaw suggests a failure in implementing robust access control mechanisms or input validation processes within the application's security layer, allowing low-privileged users to bypass intended restrictions and interact with protected resources directly through web-based interfaces.
The operational impact of exploiting this vulnerability is severe due to its potential for scope change. While the direct target is Oracle Hyperion Financial Management, successful exploitation can lead to broader consequences across additional products within the enterprise ecosystem. This lateral movement capability means that compromising one system could serve as a pivot point for attacking other connected services, thereby amplifying the risk profile significantly. The CVSS 3.1 base score of 7.6 reflects high impacts on confidentiality and low impacts on integrity, with no impact on availability. Specifically, attackers can achieve unauthorized access to critical data, potentially exposing financial reports, budgets, forecasts, and audit trails that are central to organizational decision-making processes.
In addition to data exfiltration, the vulnerability permits unauthorized update, insert, or delete operations against accessible data within Oracle Hyperion Financial Management. This aspect introduces integrity risks as well, categorized under CWE-798 in some contexts if it involves persistent access mechanisms, though primarily here it relates to CWE-269: Improper Privilege Management and CWE-352: Cross-Site Request Forgery depending on the specific mechanism of action. The requirement for human interaction from a person other than the attacker indicates that social engineering tactics may be necessary to trigger the exploit, such as convincing an employee with low-level access to click a malicious link or upload a crafted file through the HTTP interface. This dependency on user behavior does not mitigate the severity but rather shifts the attack vector towards more sophisticated phishing scenarios targeting internal staff members who have legitimate but limited network access rights.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. Oracle should be consulted for available patches or updates that address this specific security flaw in version 11.2.26.0.000. Organizations running affected versions are advised to apply these fixes promptly after testing them in non-production environments to ensure stability. In the interim, network segmentation and strict firewall rules can help restrict HTTP access to only necessary IP ranges, reducing the attack surface available to low-privileged attackers. Additionally, implementing multi-factor authentication for all user accounts, regardless of privilege level, adds a critical layer of defense that could prevent unauthorized sessions even if credentials are compromised through social engineering.
Security monitoring and logging enhancements should also be deployed to detect anomalous activities associated with this vulnerability. Since the attack requires human interaction, unusual login patterns or data access requests from low-privileged accounts during off-hours can serve as indicators of compromise. Integrating these logs into a Security Information and Event Management system allows for real-time alerting when such behaviors are detected. Regular audits of user permissions ensure that employees retain only the minimum privileges necessary to perform their job functions, adhering to the principle of least privilege which directly counters the conditions required for this vulnerability's exploitation.
Ultimately, addressing this issue requires a holistic approach combining patch management, network hardening, and continuous monitoring. The combination of high confidentiality impact and potential scope change makes this vulnerability a priority for remediation within any organization utilizing Oracle Hyperion Financial Management. By understanding the technical nuances of how low-privileged users can leverage HTTP-based interactions to compromise data integrity and confidentiality, security teams can better defend against both direct exploitation attempts and broader campaigns aimed at destabilizing financial operations through insider threats or compromised accounts.
