CVE-2026-70759 in Hyperion Financial Reporting
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Hyperion Financial Reporting product of Oracle Hyperion (component: Server). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion Financial Reporting. 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 Reporting accessible data as well as unauthorized read access to a subset of Oracle Hyperion Financial Reporting accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N).

The identified vulnerability resides within the Server component of Oracle Hyperion Financial Reporting, specifically affecting version 11.2.25.0.000 and potentially other supported releases in that lineage. This security flaw represents a significant risk to organizations relying on this enterprise performance management software for critical financial data processing and reporting. The core issue stems from an architectural weakness or logic error within the HTTP handling mechanisms of the application server, which fails to adequately enforce authentication requirements before executing certain operations. Consequently, while the vulnerability is technically accessible via standard network protocols over HTTP without requiring prior credentials, it introduces a dependency on social engineering tactics for successful exploitation. This unique characteristic distinguishes it from purely automated remote code execution flaws and places it in a category where user behavior plays a pivotal role in the attack chain.
From a technical perspective, the flaw allows an unauthenticated attacker to interact with the server via HTTP requests that bypass standard authentication checks under specific conditions. However, the exploitation is not fully autonomous; it requires human interaction from a victim other than the initial attacker. This typically implies that the vulnerability may involve cross-site scripting patterns or similar web-based attack vectors where a user must click on a malicious link, open a crafted document, or otherwise interact with content designed to trigger the exploit within their browser session while authenticated to the application in another context. The presence of this human interaction requirement significantly alters the threat landscape, as it necessitates targeted phishing campaigns or social engineering efforts rather than allowing for broad, automated scanning and exploitation across the internet.
The operational impact of a successful compromise is substantial regarding data integrity and confidentiality within the financial reporting domain. An attacker who successfully exploits this vulnerability gains the ability to perform unauthorized updates, inserts, or deletes against accessible data managed by Oracle Hyperion Financial Reporting. This capability directly threatens the accuracy and reliability of financial reports, which are foundational for regulatory compliance, strategic decision-making, and stakeholder trust. Furthermore, the vulnerability permits unauthorized read access to a subset of accessible data, leading to potential information disclosure. Sensitive financial metrics, internal forecasts, or proprietary business intelligence could be exfiltrated, resulting in competitive disadvantage or reputational damage. The combination of write and read privileges means that an attacker can not only steal information but also manipulate it, creating false records that may go undetected for extended periods if proper audit trails are insufficient.
In terms of industry-standard classification frameworks, this vulnerability aligns with CWE-79, which covers Improper Neutralization of Input During Web Page Generation known as Cross-site Scripting (XSS), particularly in contexts where stored or reflected scripts lead to privilege escalation or data manipulation when combined with user interaction. It also relates to CWE-285, describing Improper Authorization, specifically the failure to enforce authentication before performing sensitive actions. From a tactical standpoint within the MITRE ATT&CK framework, this vulnerability supports techniques associated with Initial Access through Phishing and subsequent Execution of malicious scripts or commands via browser-based interactions. The attack path likely involves T1078 Valid Accounts if the victim is already authenticated in another tab, leveraging that session context to execute unauthorized actions against the application backend.
Mitigation strategies must address both the technical flaw and the human element involved in its exploitation. Oracle has released patches for version 11.2.25.0.000 and likely other affected versions; applying these updates is the primary remediation step. Organizations should prioritize patching this component to eliminate the underlying code vulnerability that permits unauthenticated access or improper authorization checks. In addition to software updates, defensive measures should include implementing strict Content Security Policy headers to mitigate potential script injection vectors if XSS is involved. Network segmentation can also help by restricting HTTP access to the Hyperion Financial Reporting server to only trusted internal subnets and authorized IP ranges, thereby reducing the attack surface available to external adversaries.
Security awareness training remains a critical component of defense against this specific vulnerability type. Since successful exploitation requires human interaction, employees must be educated on recognizing suspicious links or requests that might trigger such exploits. Implementing multi-factor authentication for all administrative and user accounts adds an additional layer of security, although it may not directly prevent the initial exploit if the session is already established through social engineering. Regular monitoring of application logs for anomalous HTTP requests or unusual data modification patterns can aid in early detection of attempted exploitation attempts. By combining timely patching with robust network controls and comprehensive user education, organizations can significantly reduce their risk exposure to this vulnerability within Oracle Hyperion Financial Reporting environments.
