CVE-2026-87230 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 unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion Financial Management. 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 creation, deletion or modification access to critical data or all Oracle Hyperion Financial Management accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Financial Management accessible data. CVSS 3.1 Base Score 10.0 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/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 critical security deficiency that allows an unauthenticated attacker to compromise the integrity and confidentiality of the system without requiring any prior credentials or user interaction. The attack vector is network-based via HTTP, meaning that remote adversaries located on the same network segment or accessible over the internet can exploit this weakness directly through standard web protocols. The severity of this vulnerability is underscored by a CVSS 3.1 Base Score of 10.0, indicating maximum criticality due to its high impact on both confidentiality and integrity while maintaining low attack complexity and no requirement for user interface interaction or privileges.
From a technical perspective, the core flaw likely involves insufficient validation or authentication checks within the HTTP request handling mechanisms of the application server. This deficiency permits malicious actors to inject unauthorized commands or manipulate data structures that are intended to be protected by strict access controls. Because the vulnerability allows for unauthorized creation, deletion, and modification of critical data, it effectively bypasses the fundamental security boundaries designed to protect financial records and configuration settings. The ability to alter or destroy data implies a complete breakdown in integrity protections, while the potential for unauthorized access to all accessible data signifies a total failure of confidentiality controls. This dual impact on both CIA triad elements is what drives the extreme severity rating assigned by vulnerability scoring standards.
The operational impact of this vulnerability extends beyond the immediate application layer due to scope changes inherent in enterprise software architectures. While the technical flaw exists within Oracle Hyperion Financial Management, successful exploitation can lead to lateral movement or privilege escalation that impacts additional products integrated with the financial management suite. In complex ERP environments, data silos are often permeable through shared authentication services or database connections. Consequently, an attacker gaining control over one component may leverage those credentials or access paths to compromise adjacent systems, leading to a broader organizational breach. This cascading effect highlights the risk of treating application vulnerabilities in isolation when they exist within interconnected enterprise ecosystems where trust boundaries between modules are often assumed rather than strictly enforced.
In terms of industry standard classifications, this vulnerability aligns with CWE-287 Improper Authentication and CWE-94 SQL Injection or similar injection flaws depending on the specific mechanism used to manipulate data. The attack pattern corresponds closely to ATT&CK technique T1059 Command and Scripting Interpreter if code execution is achieved through data manipulation, or T1136 Create Account if new administrative accounts are created for persistence. Furthermore, the unauthorized modification of critical data maps directly to MITRE ATT&CK tactic TA0040 Impact, specifically sub-techniques such as Data Manipulation (T1565) and Inhibit System Recovery (if backups or logs are targeted). These mappings provide a structured framework for security teams to understand not just the technical nature of the flaw but also its place within broader adversary behavior models.
Mitigation strategies must prioritize immediate remediation given the remote unauthenticated nature of the exploit. The primary defense is the application of vendor-supplied patches that address the specific authentication and input validation flaws in version 11.2.26.0.000. Organizations should verify their deployment versions against Oracle’s official security advisories to determine patch availability. In scenarios where immediate patching is not feasible due to operational constraints, network-level controls such as Web Application Firewalls can be configured to detect and block malicious HTTP payloads associated with this vulnerability. Additionally, restricting access to the Hyperion Financial Management interface to trusted IP ranges via firewall rules or reverse proxy configurations reduces the attack surface by limiting exposure to unauthenticated remote actors. Regular auditing of administrative logs for unauthorized data modifications is also recommended to identify potential exploitation attempts post-patching.
