CVE-2026-87183 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 high 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 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 takeover of Oracle Hyperion Financial Management. CVSS 3.1 Base Score 7.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H).

Analysis

The identified vulnerability resides within the Security component of Oracle Hyperion Financial Management version 11.2.26.0.000, representing a significant risk to organizations relying on this enterprise performance management platform for critical financial reporting and analysis. This flaw is classified as an easily exploitable security weakness that fundamentally undermines the integrity and confidentiality of the application environment. The nature of this vulnerability allows a high-privileged attacker who has already established logon access to the underlying infrastructure hosting Oracle Hyperion Financial Management to compromise the system's core functions. While the initial point of entry requires elevated privileges on the host operating system or network, the subsequent exploitation within the application layer leads to a complete takeover of the Oracle Hyperion Financial Management instance. This escalation path highlights a critical failure in privilege separation and input validation mechanisms that are expected to contain damage even when lower-level infrastructure controls are breached.
The operational impact of this vulnerability is severe, as indicated by its CVSS 3.1 Base Score of 7.7, which reflects high impacts on confidentiality, integrity, and availability. The attack vector requires human interaction from a user other than the attacker, suggesting that social engineering or phishing tactics may be employed to trigger the exploit after initial access is gained. This requirement for user interaction does not diminish the severity but rather indicates a complex exploitation chain where an adversary might leverage legitimate credentials obtained through compromise of another system to interact with Hyperion in a malicious manner. The scope change aspect noted in the vulnerability description implies that compromising Oracle Hyperion Financial Management can lead to lateral movement or impact on other connected products within the enterprise ecosystem, thereby expanding the blast radius beyond the immediate application server.
From a technical classification perspective, this vulnerability aligns with CWE-269 Improper Privilege Management and potentially CWE-74 Improper Neutralization of Special Elements in Output Used by a Downstream Component if code injection is involved, though the specific mechanism depends on deeper analysis. In terms of adversary behavior, it maps to MITRE ATT&CK techniques such as T1078 Valid Accounts for initial access via high privileges and T1213 Data from Information Repositories or T1564 Hidden Files and Directories if persistence is established post-exploitation. The ability to take over the application allows an attacker to manipulate financial data, exfiltrate sensitive corporate information, or disrupt critical business operations by altering configurations or injecting malicious scripts into reports.
Mitigation strategies must focus on both immediate remediation and long-term architectural hardening. Oracle should be applied with the latest security patches as soon as they are available for version 11.2.26.0.000 to address the specific code flaw in the Security component. In addition, organizations should enforce strict least-privilege principles across all infrastructure layers, ensuring that service accounts and administrative users have only the minimum permissions necessary to perform their tasks. Network segmentation is critical to isolate Oracle Hyperion Financial Management from general corporate networks, limiting the ability of an attacker who compromises a different system to reach the Hyperion infrastructure. Furthermore, implementing multi-factor authentication for high-privileged logons can mitigate the risk associated with credential theft and reduce the likelihood of successful human-interaction-based exploitation. Continuous monitoring using SIEM solutions should be configured to detect anomalous login patterns or unusual data access behaviors that may indicate an active exploit attempt against this vulnerability.
