CVE-2026-70765 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 and while the vulnerability is in Oracle Hyperion Financial Reporting, attacks may significantly impact additional products (scope change). 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 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/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 platform for critical financial data processing and reporting. The core issue stems from an architectural or implementation defect within the HTTP handling mechanisms of the server, which fails to adequately enforce authentication requirements before processing certain requests. Consequently, the vulnerability allows unauthenticated attackers who have network access via standard HTTP protocols to interact with the application in ways that bypass intended security controls. This lack of proper access control verification is a fundamental failure in securing web-facing applications and highlights gaps in how session management or request validation is implemented within this specific version of the software.
From an operational perspective, the exploitability of this vulnerability requires human interaction from a user other than the attacker. This characteristic aligns with social engineering vectors where an unsuspecting administrator or authorized user might be tricked into clicking a malicious link or submitting crafted input that triggers the vulnerable code path on their machine while connected to the target system. Despite this requirement for user involvement, the ease of exploitation remains high due to the low complexity associated with crafting the necessary HTTP requests once the vector is established. The impact extends beyond the immediate application because successful attacks can lead to a scope change, meaning that compromising Oracle Hyperion Financial Reporting may provide an attacker with footholds or data access points that significantly affect additional integrated products within the broader Oracle ecosystem. This lateral movement potential amplifies the severity of the initial breach, as it undermines the isolation boundaries between different enterprise applications.
The technical consequences of a successful exploit are twofold, impacting both confidentiality and integrity while leaving availability largely unaffected according to the provided metrics. An attacker can achieve unauthorized read access to a subset of data accessible by Oracle Hyperion Financial Reporting. This exposure allows for the exfiltration of sensitive financial records, strategic plans, or proprietary business intelligence that is stored within the system's database. Simultaneously, the vulnerability permits unauthorized updates, inserts, or deletes against other accessible data. This integrity violation enables an attacker to alter financial reports, manipulate transactional records, or delete critical audit trails, thereby corrupting the accuracy and reliability of organizational reporting mechanisms. Such actions can lead to severe regulatory non-compliance, misleading stakeholder decisions, and substantial reputational damage. The CVSS 3.1 base score of 6.1 reflects this moderate-to-high severity, driven by network accessibility, low attack complexity, no required privileges for the attacker, but requiring user interaction and resulting in cross-domain impact.
In terms of industry standard classification, this vulnerability maps closely to CWE-798: Use of Hard-coded Credentials if authentication bypass is involved through static keys, or more likely CWE-200: Exposure of Sensitive Information to an Unauthorized Actor for the read aspect, and CWE-352: Cross-Site Request Forgery (CSRF) or CWE-434: Unrestricted Upload of File with Dangerous Type depending on the specific mechanism if file handling is involved. However, given the description of unauthorized data modification without authentication via HTTP, it strongly aligns with CWE-862: Missing Authorization and potentially CWE-918: Server-Side Request Forgery (SSRF) if internal services are being accessed indirectly. In the context of the MITRE ATT&CK framework, this vulnerability facilitates initial access through tricking a user, which corresponds to Tactic TA0001 Initial Access with techniques such as Spearphishing Link or Trusted Relationship exploitation. The subsequent data exfiltration and modification fall under Tactic TA0009 Collection and Tactic TA0043 Reconnaissance if the read access is used for further mapping of the environment, followed by Impact tactics involving Data Manipulation.
Mitigation strategies must address both immediate remediation and long-term architectural improvements. The primary defense is to apply the latest security patches provided by Oracle as soon as they are available for version 11.2.25.0.000 and related supported releases. Organizations should verify their deployment configurations to ensure that no public-facing instances of this specific component exist without robust network-level access controls, such as Web Application Firewalls (WAF) configured to detect anomalous HTTP patterns associated with unauthenticated exploitation attempts. Additionally, implementing strict input validation on the server side can help mitigate risks related to malformed requests that trigger these vulnerabilities. Security awareness training for all users is critical given the requirement for human interaction; employees must be educated to recognize and report suspicious links or prompts that could lead them to interact with compromised systems. Finally, network segmentation should be reviewed to limit the blast radius in case of a successful compromise, ensuring that even if Hyperion Financial Reporting is breached, lateral movement to other critical financial databases remains restricted by strong identity and access management policies.
