CVE-2026-70746 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 creation, deletion or modification access to critical data or all Oracle Hyperion Financial Reporting accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Financial Reporting accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the Oracle Hyperion Financial Reporting server component, specifically affecting version 11.2.25.0.000 of the Oracle Hyperion suite. This software is a critical enterprise application used for financial planning, performance management, and reporting across large organizations. The flaw represents a significant security risk because it allows an unauthenticated attacker to compromise the system through network access via HTTP. Unlike many high-severity vulnerabilities that require complex exploitation chains or specific user privileges, this vulnerability can be triggered by any remote actor with basic connectivity to the affected service port. However, the attack vector is not entirely passive; it requires human interaction from a victim other than the attacker. This characteristic suggests that the exploit likely involves social engineering tactics, such as convincing an authorized user to click on a malicious link or open a crafted file that triggers the vulnerable code path within the server application.
From a technical perspective, the vulnerability enables unauthorized creation, deletion, or modification of critical data stored within the Oracle Hyperion Financial Reporting database. This directly impacts both the confidentiality and integrity aspects of the security triad, as indicated by the CVSS 3.1 base score of 8.1. The high impact on confidentiality means that sensitive financial records, strategic plans, and proprietary business metrics could be exfiltrated or viewed by unauthorized parties. Simultaneously, the high impact on integrity implies that an attacker can alter these records to manipulate financial outcomes, hide fraudulent activities, or corrupt data essential for regulatory compliance. The absence of authentication requirements at the point of exploitation makes this particularly dangerous in environments where internal networks are not strictly segmented from external-facing services.
The operational impact of a successful exploit is severe and far-reaching within an enterprise context. Financial reporting systems often serve as the single source of truth for executive decision-making, investor relations, and regulatory filings such as SOX compliance reports. If an attacker modifies this data, it can lead to incorrect financial statements being published, potentially causing stock price volatility, legal liability, and loss of stakeholder trust. Furthermore, if critical configuration files or user access controls are deleted or modified, the system could be rendered unusable for legitimate users, leading to operational downtime. The requirement for human interaction does not diminish the severity; rather, it shifts the burden of defense toward security awareness training and robust input validation mechanisms within the application layer.
In terms of industry standard classifications, this vulnerability aligns with CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting or a related injection flaw that leads to privilege escalation or data manipulation when combined with social engineering. It also maps to MITRE ATT&CK techniques involving Initial Access via Spearphishing Link, followed by Data Manipulation and Exfiltration under the Impact category. The specific vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N highlights that while availability is not directly impacted in this scenario, the breach of confidentiality and integrity is total for accessible data.
Mitigation strategies must address both the technical flaw and the human element required for exploitation. Oracle has likely released a patch or update to correct the underlying code defect; therefore, applying the latest security patches provided by Oracle for version 11.2.25.0.000 is the primary remediation step. Administrators should ensure that all instances of Hyperion Financial Reporting are updated immediately upon availability of the fix. Additionally, network-level controls such as Web Application Firewalls can be configured to detect and block malicious payloads associated with this vulnerability before they reach the application server. Implementing strict HTTP header policies and content security policies may also help mitigate potential exploitation vectors that rely on browser-based interactions.
Beyond patching, organizations should enforce multi-factor authentication wherever possible for administrative interfaces and sensitive data access points within Hyperion, even if the initial exploit does not require it, to add a layer of defense in depth. Security awareness training is crucial to reduce the likelihood of successful human interaction exploitation; employees must be educated on recognizing suspicious links or requests that could trigger such vulnerabilities. Regular vulnerability assessments and penetration testing should include specific checks for this type of social-engineering-assisted injection flaw to ensure that no residual risk remains after patching. Continuous monitoring of server logs for anomalous HTTP requests can also aid in early detection of attempted exploits, allowing security teams to respond before data is compromised.
